I downloaded Creo Elements Direct Personal Edition the other day onto my Windows XP machine. When I downloaded it I opened it up and began modeling with no problems. When I came back to my computer it had performed an automatic update and restarted. Since that time every time I try to open it, I get an error message that says that there is no valid license. I have no malware programs active, and turned off my firewall. The the only thing that I notice that has changed is that my PC went through an automatic update. Does anyone have any ideas on how to fix this? Thanks in advance.
