IFF ADP Payroll GL Posting File Import Failure

We've been following the same procedure for downloading and posting our payroll's GL entries from ADP for a few years now without a problem.
A few weeks ago we received an error message [We weren't able to import your file] when we tried to import the IFF file. (error message attached)
When we follow the prompts for what's next and select the review now to look at the error report created in the IFF process we get a second failure notice saying [Problem: you are trying to open a QuickBooks file. Only QuickBooks company files can be opened this way. (error message attached)
While we can manually enter the GL to post our payroll created by ADP (our external payroll service company), we prefer to eliminate the opportunity for data entry errors by posting it directly as we had done every two weeks for the past 2-1/2 years before this error suddenly popped up.
Has anyone else encounter this type of situation? If so, how was it resolved?
