qt wallet warning transactions may not be correct ...not syncing

[quarbit]

I am running the most current version of QT Wallet and it has been fine for several weeks with no problem then today I opened my wallet and it would not sync at all,  and I am getting this message: 

Warning: displayed transactions may not be correct!  You may need to upgrade or other nodes may need to upgrade.  

I tried uninstalling and reinstalling but no change. 


What am I supposed to do?
