Log out and back into foursquare. That will fix the problem. If not delete then re-add the foursquare account.

Afraid not- at least with Tweetdeck. Delete account from TD, close TD, logout of 4square, log back in, add back to TD- first post is johnny tweetdeck again.
We will be retiring the API v1 without any exceptions on August 1st. If you are using a third-party application that was built on API v1, it will not work after that date. We encourage you to try out one of our official foursquare applications. You can see the devices we support at foursquare.com/download, where you can download our app. You can also use the mobile web from your phone's browser at m.foursquare.com.
Hope that helps!
