Only just started this, but it force closes when updating or downloading. Uninstalled through Titanium. Reinstalled an old APK, updated; no dice! Anyone else getting this? It seems that only updating or downloading forces the crash, browsing isn't a problem.
 I think Google is having issues with the Market, tapping HELP takes me to this page;
(update) I do apologise, I must attempt all possibilities before requesting assistance. If this happens to anyone else, have you installed Adfree Android? If so, this was my problem. I fixed this by reverting it's settings and uninstalling.
