Android market v 3.4.4 keeps force closing whenever I open it or if it gets that far, try to download something. I did some research and others are experiencing the same problem. "Unfortunately, Market has stopped"
I have tried wiping the app's data and cache through the application management menu. Neither seemed to work. The only fix that I've come across is the uninstall updates option in Settings/Applications. It then works for a brief period of time before automatically updating the market to 3.4.4 where it continues to force close.
