Steps leading to error:
Open wallet -> wallet begins sync
wallet seems to hang on "Current number of blocks" 270662 -> Number continues to rise for "Estimated Total Blocks"
Restart Wallet: same behavior as above, message appears in dialog

"Warning: Displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade"

I despise an error message which simply guesses on my behalf  

Wallet is encrypted and backed up.

Any assistance would be appreciated.
