This module just stopped working all of a sudden. It's been working for over a year. Nothing has changed on the server end. I get the error: "No data returned from Fedex, perhaps the Fedex site is down" I called fedex and everything looks good on their end. I checked all of the contrib files and they are current/unchanged. (and did a 'diff' on all files.) Any ideas? Please help!
