Aaaaargh! yes...I feel the pain also....unfortunately, I have tried
EVERYTHING in the wee list kurt provided...as well as
uninstalling/reinstalling, enabling/re enabling firewalls, etc...to no avail,
however, I share the PC with other people and they can all sign in
successfully to messenger...I've even set up another account!!!! It signs
in!!!!
I don't think it's just us though...a friend of mine has had a similar
problem for the past 3 months...someone told me it was because the server
couildn't read the information, because there was too much (contacts, etc) I
don't know...HELP!!!!
