I had to switch back to an older Cubase version (luckily I didn’t uninstall Cubase 6) because Cubase 8 has been very unstable when opening existing projects (previously saved with it). This first occured after I installed Cubase 8.0.30 but even when I downgraded it to the original Cubase 8 the crashes still occured. Here are the symptoms.
I neve know when crashes start happenning. Yesterday I worked the whole days with several projects without experiencing an issue. Today everything crashes (but Cubase 6 still works fine). But the same project may suddenly load succesfully again in Cubase 8 after some work with Cubase 6. I tried both 32 and 64 bit versions.
What’s extra irritating with these crashes is that Cubase process still hangs in Window (I am using Windows 7 64 bit) task bar, and I can’t even kill the process. The only remaining option is to restart the machine. My audio interface is M-Audio ProFire 2626.
Here is the crash log from the Windows event viewer:

Hope this helps to identify the problem.
