Please help! Focusrite Mix Control crash when lauching Producer X3d - SOLVED

I don't know if toggling this might help...
Preferences > Audio > Playback and Recording > Share Drivers with other programs
 
The other setting that might be worth toggling as an effort to fix the issue might be...
Always Stream Audio through FX
on the same tab.
 
These are the things I would try.

Focusrite has a new update. Ver 3.4
I dont know if its only for Saffire or for other interfaces.

The beta version of focusrite is now a full version 3.4
 

The only mystery here is that only x3 is crashing. Otherwise you'd be looking at the Focusrite drivers. And this just might be the case. 
I'm a little miffed at them as they seem to be under question with driver releases. When I bought my  scarlett 6i6 I went to the web site and downloaded  1.7.
Like yours this includes the driver, the Mix control software and firmware all in a package. I installed this and when I plugged the Scarlett in, Windows7  told me it was installing the drivers? Then it said there was a problem and my hardware might not work?? Then The scarlett opened a window to say it was updating firmware to new version.
Nothing worked. I spent 2 hours mucking about.  Still dead ,, so sent an e mail to support.
In the meantime I grabbed my wifes Lenovo Laptop and re downloaded the drivers and boom, it worked just fine??
Later that day support replied to tell me they had removed 1.7 from the download site as it had "issues" and posted me a link to the Beta drivers?? 
I checked my download on the laptop, sure enough, it was 1.6??  I just checked yesterday and 1.6 is still there on the support page. That version is known by them to be buggy.. so what's with keeping buggy drivers posted?? Not only that, if you want the ones that work, Beta 1.7,  you'll only get them by contacting customer support. I could not find them on the web site.
Anyhow all is working just fine with the beta drivers, but to me that's a little weirdness.
 
So long and short of it is  "Focusrite MIGHT have questionable drivers" . Or the Mix Control software is buggy. Not sure if it's universal to all Focusrite products. And why do they bundle it together. I would prefer a sperate down load for each of the 3 items.

The sample rates are set correctly, and I'm using the 18i20 clock as the master, with BNC connections to the Presonus and the DBX.  I had them daisy chained, but I have ordered a T connector and will try running lines to each preamp and terminate them both.  When they were daisy chained, the DBX was the last in the chain and was terminated, but the Presonus wasn't. 
 
I agree about the frustrations with Focusrite bundling everything together.  I wanted to roll back the drivers to see if an earlier version would work, but wasn't able to. They also have not been very quick to answer my support ticket.  I contacted them 5 days ago and still haven't received a reply. 

MY rig is a bit more simple ... still, I have issues my 18i2 ...it will fail to "close" when shutting down WIN7 thus causing some sort of loop which eventually crashes the computer ...I've read Focusrite units have similar problems across the product line ...don't know that for a fact ...

I would not trade the 18i ...it's performance is very good ...despite the occasional hiccup...

.

I would hope it's not the norm.  I'm sure it's something amiss in my system.
I'm downloading the optional updates now and will give that a try.  There are also a few motherboard updates that I need to install.  I'll let you know if that helps.
