Sage 100

1099 Printing - get message FEIN Mismatch - There is a conflict blabla - looks like an Aatrix screen. Company maintenance and 1099 printing have the same FEIN. Latest SU and IRD installed. I have several systems doing this - not figured out what the issue is.

Try renaming the eFiling folder under the mas_xxx company folder

Worked!! Thanks @MaryJoKrueger

Renaming the eFileReporting folder certainly is solving a LOT of issues this year. Not a good sign!
