Trados asking me to activate and old code doesn't work - issue me a new one?

I just tried opening Trados and was asked to activate again. I tried copying and pasting the code that I was provided with, but got an error code. I need a quick fix here 'cause I have rush jobs to deliver. Can you help me? See below for error pop up. Perhaps I simply need a new activation code? My motherboard was changed since my last use and perhaps this is why I can no longer use my software.
