Workbench Access to MySQL migration issue.

MySQL Workbench version: 6.2.3.12312 Build 2280 32 Bit
Win 7 pro, latest patches.

I am trying to Reverse engineer a MS Access 2010 DB to a MySQL DB. I get to the reverse engineer part and it almost gets done and then throws the following error. I don't know where to go from here, the error doesn't provide me with any info to work with. Does anyone have any idea as to what my issue might be?

Thanks,
