hi,
Same thing happend to me just now after upgrading the systems RAM i had a nasty crash with VS 2008. it was constantly coming up with the VS 2008 has experienced a problem and every time i selected send or do not send, it would still pop up, i restarted the machine and then the server explorer would not come on. i had this error message in the output window
The Visual Studio Explorers and Designers Package ({8D8529D3-625D-4496-8354-3DAD630ECC1B}) did not load because of previous errors. For assistance, contact the package vendor. To attempt to load this package again, type 'devenv /resetskippkgs' at the command prompt.
to fix this type devenv /setup into the command prompt under VS2008 > VS2008 tools > commad prompt.
i know the chaps above have alredy stated this but i want people to know that this is also the fix for VS2008
