I think I found something, is this what you meant?
" agree that Toontrack did a poor job with this release, and the support was disappointing. I will say that I was able to resolve the issues (so far, at least) by doing the following.
1-Completely uninstall EZDrummer
2-Reboot, do not start Sonar, and re-install EZDrummer 2 AND ANY UPDATES.
3-BEFORE OPENING YOUR DAW, open EZD2 in stand-alone mode and select the Sonar option from the menu in the upper right.
4-Now when you start Sonar and when you open a project, you will get a dialog box asking how many outputs you want. I always choose 8. I'm not sure what others do, but I never need more than 6 EZDrummer tracks, so 8 seems to be good.
I can't say what will happen to you, but many of us found this to work well.
I made a huge mistake by not setting a Windows Restore Point before first installing EZD2. I will never make that mistake again. I now set a restore point before I install anything—and I name it something meaningful like "Before_MiniV" or "Before EZD2" or whatever."
I'm going to try the above and keep my fingers crossed.
