Flo Crashing on Vista 64?

Just transfered my flo license over to my vista 64 quad corelaptop, and can't seem to get any simulations to run.

Flo loads fine, but crashes right before it starts its firstiteration.

The same files/setup runs fine on my winxp32 machine with nohickups... anyone had issues like this???

Thanks,
