When I launch the 64-bit version, program execution stops just past the splash screen resulting in a blank (white) window.

The 32-bit version runs just fine.

I'm running Windows 7 x64 on an older (but *very* stable/clean/fast) Intel i7 950 system with 16GB RAM, 250GB SSD system drive and NVIDIA graphics driver.

All my other audio programs such as Cubase, Sonar, Notion, Kontakt, etc. run flawlessly.

Cheers...
