I am trying to join an excel table to a layer file and get a message - Failed to connect to database. the user and/or password is invalid. Cannot start your application. The workgroup information file is missing or opened exclusively by another user.
I am on 10.2.2 - table is an .xls table.
I have tried a new .mxd, altenate tables, saved the table to the local drive - all produce the same error message.
This was working on Friday afternoon and Monday - not working :-(
