The pop up shows up for about 3 seconds and I can't even do a print screen of it.  Just doesnt appear in the image.  
 
But it hapens every time I exit from the preferences.
 

Here is the "Generic Driver" in the list.  Cant do anything with it, but it keeps showing up whenever I close preferences.

I have the RME unit and I have come across the problem you describe. I was able to chase it down to a MIDI device (Fishman Triple Play) in standalone mode. However I don't believe I ever came across it while utilizing the device while I was in Sonar. As Karhide mentions make sure your preferences are set.
 
And make sure that your MOBOs sound card is configured correctly. On my DAW that item is disabled, disconnected and dissed permanently.
 
Hope you get it figured. Regards,

I have disabled all midi devices in SONAR.  Still having the problem.
 
Its not running in Class Compliant mode, because TotalMix is working.

This software has a very "garbagey" feel.  Will give another 15 minutes of my time then write this POS off as a loss.  Shame  because the upgrade is cheap for former SONAR users.
 
Also, why do you need two separate tracks for a VSTi?  Samplitude has combined midi/audio tracks, just enable a VSTi and everything works.  Things that make you go . . .

Then use Samplitude. Problem solved!

Grass not greener here. . .

I am using a UFX and my drivers are defined as expected. I would try to uninstall the drivers and plug the UFX as a USB device with up to date drivers and BIOS. You are doing something wrong.. Start from scratch with your UFX driver setup.

You are blaming an innocent party. This has absolutely nothing to do with Sonar. You need to sort out your drivers/hardware/pc config as others have said. All good advice here. Sure this isn't ASIO4ALL? Maybe JRiver media player? You need to get rid of that. A piece of software may be conflicting. Cheers.

SONAR has simple instrument tracks as an option - I use them all the time for one input/one output soft synth instances, though if you spent a bit of time with the program you would realize there are benefits to SONAR's approach of separate tracks for MIDI and audio. 
Your attitude blows (and the "garbagey" feel is from your post) - "Things that make you go..." (At least figure out whether or not a feature exists before you dismiss the program for not having it).
Enjoy Samplitude. Bye bye.

Or use the simple instrument track. You can even drag an instrument in from the browser and it will open up a dialog box for you where you can specify combined MIDI/audio, separate, where you want this in a track folder, etc.
