After clicking the Launch button and entering in my Adobe ID and password, I press Activate and there is an error that says that the 'Request Expired.' My ID and password are both valid, though. Please help!

The clock or the timezone is off on your computer.

Thanks Jim! Both were off, or at least according to Adobe. Arizona is technically in Mountain Time, but I had to switch it to Arizona Time and then adjust the clock.
