I went to my market a few days ago and had some updates and selected update all. Everything downloaded just fine and other update since then have been fine but Fourquare is stuck in the "starting download" stage. I have tried clicking it and canceling the download, but every time I do that it force closes the market and wont let me cancel the download. I have also gone into setting>application and force stopped the market and foursquare and still doesn't do anything. Is there anything else I can do to get this update or get it past the current stage?
You can go into manage applications, hit the All tab, find Market and select clear data. You wont lose anything or any settings, you just have to re-agree to the market terms the next time you launch it.
