Worked Yesterday - Lockup on Initializing VST 2.x Plugin

I swear, I can’t for the life of me figure out what I changed.

Have the latest version of Cubase loaded and patched. Everything worked fine.

I loaded Sony Vegas 12, and was dealing with some lock up with it on VSTi’s. But fixed that.

Was then working again happily in Cubase.

Now, I fire up Cubase, and it gets locked up on random VST 2.x plugins during initialization.

ik Multimedia CSR reverbs one time, then DMG Compassion another time. It seems to be different VSTs each time.

Seems to be getting stuck in CSR Reverb now.

However, I can load Wavelab 7 x64 bit, and it fires up just fine.

Any ideas out there at all?
