Hello! I've encountered this problem:

I've just got a new computer so I would like to deactivate my license on my previous computer. I'm a student by the way. The thing is, I want to transfer the license but I can't open Solidworks on my previous computer because I get an error like this : Failed to initialize ........ something something.... are you low on disc?. Secondly I tried to tranfser the license by login into my account here and download the activation wizard. But for some reason my serial number is invalid so I cannot register my products. Finally, I tried to start the Solidworks License Manager but as I've noticed this isn't the ''right'' one. I opened this going through the map Tools.

Can anyone help me out?
