user9043: I have been using bitcoin-qt for about 7 months without any problems until a few days ago when I launched it and a message popped up saying I should upgrade. So I did, to bitcoin-qt (v 0.8.5). Now all I get is "Synchronizing with network" (Processed 0 of 250284). I have left it for hours and its not changing. I have checked my broadband speed and Im getting approx 7.5 meg. Any Ideas? 

user11740: I have had the same issue. Instead of deleting blockchain data, I found that you can run the application with commandline arg to reindex and rescan:
/Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -rescan -reindex
