Something has changed. Accessing files from within Maya doesn't work any more, when I try to open a file (File>Recent files>etc) Maya goes through the motions but nothing appears. If I go the file via Windows Explorer and double click on the file, a new Maya starts up and the file opens as normal. It looks like I've corrupted something so how do I fix things so that I can get files from the File menu? I'm running Maya 8 in Windows 7
