Problem Removing Join with 32 bit Python 2.7

To All Python Programmers:

I had a python script to update a feature class in a personal geodatabase using a join to a table view which works fine at 10.0 with Python 2.6. I am now trying to run this script on a 64 bit Windows 2008 Server using the 32 bit version of python 2.7 since personal geodatabases are not accessible with 64 bit python.

I am crashing the script when removing a join with the following error message

"ERROR 000800: The value is not a member of l ALIASES."

Has anyone ever encountered this error message and been able to resolve the issue?

Any help or hints in regard to this issue are greatly appreciated. Thanks.
