Gaming A bunch of appacrashes

[Gerinych]

Argh. I posted this somewhere else, but I'm still waiting for a reply.

So I did an upgrade from Windows b7100 t Windows b7600 and ever since I've been getting a bunch of random crashes, mostly in games. They were working fine before the upgrade, so don't ask. And just now I was trying to open UMDGen, and it crashed, yet it was working fine even after the upgrade. The only thing I remember doing between using UMDGen is using RegCure to clean up my registry, but I did that to try and fix those crashes.
Any help with this?

EDIT: Forgot the log:

Update to the full version.
Update to the RC.

Your choice choose one.

I can't really choose either one, since I have the full version right now and I can't downgrade to RC.
