Question: lost access to maple help (V11.02)

I'm running Maple 11.02 on an intel mac. I can no longer access the help menu search function or access any help topics for that matter. Also, if I hover over the 'help' pulldown menu, I get the spinning pizza of death. Reluctantly, the pulldown menu works but I still can't access anything other than a description of maple help. Thanks for any comments, Court Ashbaugh
