UBB.Developers Forums UBB.threads 7 Development How Do I? Deleting Members Problem

I am running UBB 6.2.1 and I am trying to remove inactive members from my board. I do this through the control panel. After I delete them, I clear cache, rebuild forum stats and member stats. But the problem is when I go to the board I get a back trace error referring to a member number I have deleted. If I replace the member files, the board works fine. Any help would be great.

here is what I get
