So I've seen that other people have had this issue and I can't remember if there was a solution to it, but my Bandlab Assistant is just showing me a loading screen and not letting me do anything.  I've uninstalled and re-installed it and it still shows me the loading screen.  Has there ever been a solution to this found? or is it just in time it'll correct itself?

I don't know if what I experienced is your situation, but it might be. When I opended BandLab Assistant and clicked to have it update itself, two smaller windows pop up behind the app window, so they can't be seen unless you drag the app window away. Once you do that, you'll see the front small window (a dialog box) has a message something like "BandLab Assistant is running, click OK to close it." and you have the option to click OK or Cancel. This message confused me the first time, I thought closing would stop everything, so I clicked Cancel (not that Cancel makes any more sense, but...). Wrong, that stops everything. Perhaps the message would be clearer if it said "BandLab Assistant is running but needs to close before the update can proceed. Click OK to close it and continue with the update, or Cancel to cancel the update." When I clicked OK, the app window and dialog box closed, and the remaining window, which is the installer itself dutifully waiting until BandLab Assistant closes, started installing and finished within just a few seconds. Maybe this information will help you (or anyone else) if that is what is happening to you.
 
It would be even better if BandLab could modify the installer to close Bandlab itself, which would eliminate the need for the (hidden) dialog box and just forge ahead with the install of the BandLab update.

I wanted to check and see if anyone else is still locked into demo mode. Believe me, I've  tried everything. Have had help from the top. Tried again last night. Still locked into demo

 
Did you try installing cakewalk on another computer to see if you experience the same problem?

Eddie,
I've  tried everything......wait, I  guess I  haven't  tried everything......or it would be working. Band lab tech says it sounds like the release of older install is not happening. Right now, as stated the install page shows melodyne checked and uncheckable is not available. I have been using the A drive to store all things, instead of c. I thought that might be the problem since Band lab defaults to c. But now being able to install any where should not be a problem. Everything loads to a ok, just remains in demo mode with the notice to authorize via Band lab Assistant. Already logged in. Oh well, Platinum still runs fine. That's  what doesn't make sense, unless melodyne is really causing problems
Thanks all for listening, a little frustrating

Sorry Eddie,
I have no other comp. This is my mainstay, studio only, comp.
 

Contact support make sure to let them know which OS is running and the error code from the CbB about screen. The error code will look like (a000, 0) or (2000,0)

Downloaded, updated, it#s working  smooth and fine. Thank you, Nerds and bakers :) 
I raise my glass á votre santé :)
 
Cheers !

Favorite enhancement: the interleave and phase buttons are now back in the track header where they belong. Thank you, Noel!

I see these buttons in the  header of audio tracks- but I see them in SPLAT in the same place, too.  Seems, I missconceived something . . . 
 
Cheers :)

Thank you for your help.
But - 
I don't have these Buttons in that header, neither in CbB nor in SPLAT. I see these Buttons in the header of audio tracks in the  Channel Strip in the Inspector as well as in the Mixing view. CbB is 2018.05 Buildt 19. 
 
Cheers 

scook,
This is what I sent to support. Even Noel has had me diagnose this with uncertainty. He said he might want me to run more test. Haven't heard in a while. Testing showed that comp was running ok, with all test passed. but he didn't know why their software was not responding the same way.
