Restart bitcoin-qt
==================================================
Then if that doesn't work...
-backup your wallet
-delete everything in your appdata\bitcoin folder except your wallet (the same folder that has bitcoin.conf)
-reopen bitcoin-qt
==================================================
then if that doesn't work...
run this from a cmd window
C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe -checkblocks=10 -checklevel=1
==================================================
Then if that doesn't work...
-uninstall bitcoin, delete everything in the appdata\bitcoin folder
-reinstall bitcoin
-run this from a cmd window
C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe -salvagewallet c:\backupwallet.dat
==================================================
And that's all I got for now
