Error during Recycling in VB Form

I have encountered an error while attempting to Recycle my custom fields in the Vantage Basic Forms Design area. The recycling started, and the following status messages appeared:
Building table list - finished
BOLHead - generating new flags.
BOLHead - clearing existing data.

At this point, I get the following error:
** "ClearBOLHeadData" was not found (293)

Upon pressing OK (the only option) Vantage completely shuts down, then restarts itself.

BOLHead is the table which my first form uses. We are using Progress version 9.0B, and Vantage version 4.00.815 09/22/00.
Are there any ideas as to why this error is occuring, and what can be done to deal with the problem??

Thanks for your time,
