Can't use my main computer; '?????' - not a valid win32 application I wonder if anybody has had a problem like I'm having and can help. No matter what program I try to open, I get an error telling me that "'?????' is not a valid win32 application" I can't click on anything on the desktop, not even the virus scanners or the firewall or the registry editors or even the internet browsers. Without being able to click the browsers, I won't be able to download any fixes. I can't even start my internet connections, wireless or otherwise. As soon...
