MoI v01 Doesn't accept License key after reinstall

 From:  Oseegee (OCGEE)
I recently had to reinstall MoI version 1 back onto my PC (I am saving up for version 2 =) but while MoI worked fine before, now upon starting the program, a "welcome screen" pops up and asks for my license key. Unfortunately, absolutely nothing happens after typing in all of key numbers or after I paste in license key and press "enter." It seems the computer does not recognize my input at all and simply does nothing. Does anyone have any suggestions?
