On SD it says:
 
Total: 923MB
Loaded: 0MB
 
How do i force it to load? All paths to samples are correct, all routing (input/output) are correct too.
I've used SD2 on Sonar PE7 and it was not like this.
 
(On standalone, SD2 works fine and loads.)

And does Sonar X1 have issues loading projects saved from Sonar 7?

I just installed Sonar X1 ( up from 8.3.1 ) and I am having the exact same problem.  It works fine in Toontrack Solo outside of Sonar though. And of course it works fine in Sonar 8.3.1 .

Anybody got a fix for this ?

Scratch that ! Now SD2 won't load in Sonar 8.3.1 either now that I have installed Sonar X1 as well without deleting 8.3.1 .

And now EZ Drummer Won't load in either version. Ugh

Chilblain, don't do anything else before you've installed the updates for X1.

I take it your running 64 bit, I experienced the same when I switched to 64 bit too. Two choices, load 32 bit and that will solve, runs really well on my system, no plug in crashes or search J bridge on the web, their site shows how, the demo worked, about $20 USA to license.

The OP also posted to this thread, which has a few more answers. Looks like it was solved but not certain.

To summarize:
 
1: You need to download the latest updates from your toontrack account, which will include the 64 bit versions. You need to update the 32 bit, THEN install (update) the 64 bit for everything to work.
 
2: If you are running anything 32 bit in a 64 bit host, BitBridge will NOT work - Kits won't load. You can try jBridge instead as mentioned earlier in this thread. However, if you have the latest versions you shouldn't even need jBridge.
 
There have also been many other posts about kits not loading, and the answer was to run X1 as an administrator. I'm not 64 bit so I'm not 100% sure, but I know I have come across that in these forums. I'm sure a forum search will reveal this.

Err, Bitbridge WILL work for certain 32 bit apps (VST's) in a 64/64 bit host/Sonar enviroment. For those that it can't handle, jBridge, as you say, does the job nicely.

I could never get SD2 to work in X1, so replaced it with SD3 in all my projects. That being said, for my 2 Euro cents,  I think SD3 is superior.

codamedia is right.. if your runnig 64bit it needs to run as administrator...i had the same problem..
