FAQ: The RBCA Tool Kit fails at startup. What does "Run-time error '91': Object variable or With block variable not set" mean?

This occurs when the RBCA Tool Kit files are corrupted, most often the result of improperly closing the RBCA Tool Kit. The user must reinstall the RBCA Tool Kit from original media, and should take care to always close the RBCA Tool Kit from the "quit" button located in the lower right hand corner of the main menu, and not by simply closing excel.
