Hello,
I have been runnning X3 Studio with both EZDrummer and Superior Drummer with no issues. I installed Sonar Platinum recently. Both of the Toontrack plugins still work on their own or in X3 but in the new Sonar they open and even respond to midi notes visually but don't have any sound. You can see the drums animate with each hit but the samples loaded show 0Mb instead of the actual size of the kit.
I reloaded Windows because of multiple issues and reloaded all of the Cakewalk software. When I load EZDrummer just now it behaves the same way. This tells me that it's not due to OS corruption. Everything else seems to be working just fine at the moment.
Any ideas? Is there an issue with Compatibility between the new Sonar and Toontrack?
Please help!

I've used both in Platinum without any issues.

I figured it out! My copy of the ToonTrack plugins only installed the 32 Bit version which does not like to run in a 64 Bit DAW. I am downloading an update now and will see if that works.

That worked so this issue can now be resolved. When I had originally installed the Toontrack software, I only had 32 bit as an option. They have since updated it and I wasn't smart enough to check :)

DOH!
