VBA automation error - Invalid forward reference - excel

Question

I have a code that has been running just fine, however, suddenly I am getting the following error:
I get the error in all the old files as well, even after completely shutting down excel. I also tried adding "AccessibilityCplAdmin 1.0 Type Library", which helped at first but doesn't anymore.
The error is in line "dData(dr, 1) = sheet.Name"
Does anyone know how this could be solved?
