Similar problem here: Win 7 64 bit, Pro purchased and installed, licensed and registered appropriately. But the Infinity foot pedal only showed up for a few minutes, both in the Test window, and work practically, but just for a few minutes, then stopped forever.
I deleted the Pro ES, reinstalled, same thing. Whenever I restarted the computer, the Infinity pedal worked for a few minutes and stoped, again and again. Please help. Thank you.
