Man,
This PC has a lot of bugs....
Given that I hardly ever use the PC it's no wonder I'm fat, dumb and happy.
As someone who actually
is fat, dumb, and happy, I can assure you, you are not fat or dumb. Happy, maybe.
Come to think of it, I almost never use Dim Pro, Session Drummer, Z3ta+ or Rapture; I wonder why I even own the Pro-Ducher version? 
All I use are the plug-in's and synth's that come with Sonar Producer Edition. I use 1 Free Synth (Kontakt with the free Prizm Add-On), 2 Free plug-in's, and I bought Guitar Rig 4. But 99% of what I use comes in the Producer Edition. And let me tell ya pardner' ... it can be maddening when you try to use all this stuff with all these little bugs here and there.
I'm running in to driver problem now with my Fast Track Ultra.

It does not like it when I use the power supply, but I have to for Phantom Power. I keep getting actual BSOD's. You know, the 16 color white text on blue background DOS looking screen ... in Windows 7! :) Why am I smiling? LOL! It never did like running off the DC power pack from day 1, but I didn't realize what the problem was until it was too far past the return period.
I got my portable rack unit from Amazon the other day. Now I have to go get my Mic pre out of storage and hook it all up so I can get rid of this damn DC power pack on the FTU. One of these days I have to get a new sound card, but I can make this work.
