My foursquare code suddenly stopped working. Does anyone know why this happened.

Not sure at what point in the usage cycle you're getting this from, but it's unrelated to the library.

Seems like either:
A.) Your requests are going through some sort of ISP proxy that's jamming you up
or
B.) Foursquare is having issues on their end

Library was just tested 5 minutes ago and returning valid responses.
