DTS Package: EXCEPTION_ACCESS_VIOLATION When Saving

My team is getting this message when altering a DTS Package, using SQL 2000 DTS Designer. We have downloaded all the SQL updates (Backward Compatibility, and the one specifically for DTS Save problems. Have tried this in SQL2005 as well. Have uninstalled both of these programs, and reinstalled on local machines. No avail. Here is what happens:

1) Editing an existing DTS Package, such as a Text Change, or simple connection change
2) Saving the file creates the exact message below:


Package Error
Error Source: Microsoft Data Transformation Services (DTS) Package
Error Description: Code execution exception: EXCEPTION_ACCESS_VIOLATION

3) Then you have to choose OK in the windows Popup Box.
4) The DTS is brought back to the original screen, or completely exited out of Designer.
5) From that point, the Package can no longer be opened for editing, unless you open a previous version (which means changes aren't saved.

We have also tried to SAVE AS another filename. This doesn't work either.

Our team has close to 75 DTS Packages, some simple, some more complex. We are corrupting these left and right. This problem happens no matter what is created in the DTS Package.

This is running into our business operations, and we are unable to find out a resolution...HELP

Any insight in this would be greatly appreciated.

Thanks,

Jason
