I recently downloaded and installed the WF4 Student Edition on my home computer. I have a new HP8530w so Pro runs fine. If I modify options and save a config.pro file, ProE will fail the next time I try to launch. I get the following error "Serious internal error; cannot continue" If I name the .pro file as something else and try to load it from the options menu after launch, ProE will crash when I hit OK or APPLY. Being unable to modify and save a config file makes using the software very difficult so I would appreciate any advise. Regards
