I am having trouble with foursquare. I have had it on my phone for a year and all worked well. But recently when I click the icon it sends me to the sign in page. When I sign in I get a message "welcome to foursquare!" in a black box that goes away and I am on the sign-in page again. When I attempt to uninstall nothing happens and the program remains. So I currently cannot log in or uninstall. Any suggestions?
