Hi, I am running Windows XP SP3 and have been using Mozilla Thunderbord for 1 year without any problems. Today when i started Windows and double clicked on the Thunderbird icon on the desktop - nothing, just the "windows error sound". No error message, just the windows error sign. I also located the thunderbird.exe and tried to start the program from there - same thing, just the sound. Googled, read about safe mode, tried safe mode "RUN: thunderbird.exe -safe-mode" etc - same problem, just the sound but nothing happends. So I can no longer start Thunderbord from the desktop or the catalog, and I cant start safe mode either. Thunderbird is not running under "processes" either... Please advise?
