VBA Automation Error

[MikeDBMan]

All of a sudden one of my macro workbooks starts producing an Automation error when I execute this command:

Sheets("Categories").select

The rest of the error message is "Invalid forward reference, or reference to uncompiled type".
I tried renaming the tab and I've verified there is nothing else named "Categories" in this file. I have no idea why this is happening. Any suggestions?

have you done a full restart ?

Yes, many times. This started happening a couple weeks ago. I've recompiled, restarted, renamed and yet it persists.
