This will sound weird but the way I fixed the crashing problems was to do an uninstall of both WB and Skinstudio and then reinstalled:
1. In Display Properties set "Prevent WindowBlinds from loading on startup".
2. Reboot.
3. Go to Component Manager and uninstall both WB and SkinStudio
4. Reboot.
5. Go back to Component Manager and reinstall both WindowBlinds and SkinStudio.
6. Reboot.
7. In Display Properties remove the check in "Prevent WindowBlinds from loading on startup". (Truthfully, I don't remember if I had to do this).
I don't know why it worked but I haven't had a crash since I did it.
