Error Message

Hi there, While working on a project in Solidworks Standard, I got an error message out of the blue saying "sldanalysistools cannot be loaded.  Either the Add-in or one of its components is missing".  When I click on the "OK" button, the message wont go away.  Its stuck at that error message.  No matter what file I open, I get greeted with that message and it wont go away.  Any suggestions?
