64 bit Vista

Cannot seem to paste into AE CS4 from Mocha for After Effects 2.0.1. I created a solid with a corner pin effect, but the paste is greyed out. Any tips?
i7, 9 megs of ram, size and frame rate match.:eek:

I just started playing around with Mocha and so far so good from my end… i7 920, EVGA x58 w/ 12 GB RAM and no issues.

Thanks, ok for me as well
