trouble with block download

[darkfire]

i havnt had any transactions for weeks, my client is stuck on block 137998 and hasnt updated for a while.  i have tried -rescan and uninstall, and am not running security essentials or any firewalls.  anyone have any ideas or ran into this before?  this is really putting a dampening on my mining and im pulling my hair out trying to figure it out.  any help would be greatly appreciated

Backup your wallet.dat remove everything in your Temporary Bitcoin Folder (Win: %appdata%/bitcoin, Linux /home/%user%/.bitcoin) and re-install.
