Just updated to 8.0.3. I have the Mbox 2 Pro so I didn't install the 8.0.4b driver update. Seems to work fine on Win7 Ultimate x64.
It sure would have been nice to have ANY indication this compatibility update was coming as I just rebuilt a Win7 x86 drive just for PTLE due to the incompatible driver issue.
But, at least it is here now. I hope it works for everyone else.
Other info:
Asus P5Q SE2/Q9400/4GB RAM - now going for 8GB since PTLE works in x64
