As of this moment, at 0830 EST on 26 May, 2011, Skype has committed suicide. Tune in for updates as to when the frakin' thing will be back!
UPDATE: GeekFurious super techs have found a solution. Go to:
C:\Users\Username\AppData\Roaming\Skype and delete the file shared.xml
This should let you log in (the "Username" portions should be YOUR username).
If you are still having problems, Skype has more detailed instructions HERE.
P.S.
New Bon Iver rules!
