I have documented that error a couple of times, and it loosely translates to "Reading beyond 'from the end of file". VirtualWorldDynamics can help you, but it could be a possible error from different situations.

Please, can you describe what you were doing (workflow, buttons pressed, etc.) which led to error pop-up, so VWD may help you better. Also, your PC environment to help narrow down variables.
