I just installed Creo 3.0, and it worked flawlessly for the first time. After I turned my PC back on after going to bed, I attempted to run Creo 3 from the desktop icon, and it just gave me the windows loading icon for several seconds until stopping. No error message or anything. Is this a problem that can be fixed in any other way besides re-installing? I have already done that several times, and to no avail.
