Did you ever find a solution to this problem? I am having the same problem.

Strange enough it succeeds most of the time and it's fairly difficult to reproduce the problem, but when redoing a TABLEUPDATE() after a failed transaction might cause this error. I suspect it has something to do with 2 tableupdates on the same table during a transaction but I was not able to get a clear case. Nontheless I suspect a bug in VFP 8 since the triggers called are just RI triggers and AFAIK do not contain any bugs that could cause this error.
