Trying to download solidworks. I click register my products, copy paste my serial number, select my version, and then click OK. It says my serial number has been registered like all is well. But there I can't do anything with it. It doesn't say "You didn't pay your bill", or "You need to give us more money", or "someone hacked that number, call us to get a new one". It just simply fails to have any result after registering successfully and saying it is accepted.
