Importing Assets: 'Maya could not convert mb file to an fbx'

I'm working on a project with a couple other people. Each time the engine has to import new assets it takes a ridiculously long amount of time for each individual mb file, and when it finally finishes I have a list of errors for the majority if not all of the mb files saying "Maya could not convert mb file to an fbx". I understand it may be an fbx exporter issue as I am using Maya 2011 and the other artist on our team is using Maya 2012. However, I am the only one who has this issue, and even my model files seem to have this problem. Does anyone know what is wrong? Any options to resolve the issue would be greatly appreciated.
