I'm not sure I follow what's going on here.

When you say you "moved everything" what exactly do you mean by this? Did you install Sonar and plugins on the new PC using their installers?

I moved all of my files (application, project, audio, samples, etc.) to new hard drives.  I was essentially trying the "copy your hard drive" method of moving things on to my new machine, but that's probably where things went awry.  I did reinstall AD2 a few weeks ago via their installer, but that hasn't fixed the problem with existing songs - I can get it to work in new files, but not old ones.  TH2 is just not showing up at all in old tunes, either.  Funny thing is, all of my plugins work as standalones; just not in SPlat.  I'm downloading the new Command Center now and was going to try reinstalling everything again to see if that works.  I'm just perplexed that I see TH2 getting a signal to process but not sending anything to my outputs.  same thing with AD2.

yea, thats what i left out, i apologize. I did that same thing, i attempted to copy everything from the old harddrive.. didnt work as planned. I then downloaded CCC on the new hard drive and installed, i never deleted the Sonar program folders that i copied from the old hard drive.

The only thing i can really recommend is just download the CCC then install SPlat. Also reinstall AD2 from the online installer. Thats what seemed to work for me in this similar circumstance. I don't know if anyone else here has any other ideas they can come up with lol

Copying applications from one Windows installation to another rarely works because the new Windows installation won't have the necessary registry entries and probably will be missing other things as well. For example, the hidden by default Program Data and user profile directories contain quite a lot of stuff essential for some applications to run correctly and it's very easy to miss things.

Data (projects, pictures, audio etc.) you can just copy and will be fine. Applications (including plugins) need to be freshly installed using their installers otherwise you'll get the kind of problems you're having.

This is a function of how Windows works and is not a Sonar problem.

You can rebuild a Windows installation from backup images to an extent, but that's quite different to just copying stuff on to a new PC.

And I nearly forgot - some things use hardware data like network card MAC address, or motherboard serial number, as part of their licensing system. Just dragging them around to different PCs is exactly what that kind of licensing is intended to prevent.

^^ what he said, prolly why when i reinstalled everything it corrected the issue.

Thanks, guys - this is all super helpful.  I'm going to start the reloading process as soon as I get home from work.  Stay tuned...

Ill still be here... i have no friends HA

I reinstalled/updated everything in CCC so all the lights are green but nothing has changed in terms of my ability to actually use SPlat.  XLN Installer says everything is up to date.  I'm at the end of my rope.  Perhaps the nuclear option is all that's left for me: uninstall EVERYTHING and start over.  It's been a month and I'm just done with it.

Make sure the XLN installer is pointing to your NEW hard drive (maybe disconnect your old one.)  You may need to "unlicense" AD2 on your old one because I think you can only have 2 active installs.
