I recently installed Solidworks Student Edition 2010-2011 and registered my copy.  Solidworks ran the first time it was installed and I drew things without problems.  After that the program refuses to open.  I get the splash screen for about 15 seconds and then it goes away without ever opening.  I have uninstalled, removed files and registry entries and then re-installed and it worked the first time again (but only the first time).  If I don't remove the registry files during the uninstall then even if I re-install it will not run. I think something with the licensing manager is malfunctioning.  Any ideas?
