I guess there's a third possibility I should add to the list above: picking the wrong game system to activate for your license!
Since Pathfinder and M&M3 are adjacent in the list, it was probably a simple and unintentional oops to pick the wrong game system. That's something that Colen can get corrected for you quickly, after which you should be off and running.
I'm glad it was something easy for us to fix for you!
