The specified file format is unknown when running SIR report on SAGE 200 version 9

Hi.

We recently upgraded to sage 200 version 9.2. Initially we had view issues on our SIR reports, but as of yesterday one of the reports only is gicing the above error message. What I have tried to date

1. Opened the template and saved it to the report again.

2. Removed all addins from the template

3. Changed the file extension to capitals and small case as suggested by an old KB

4. Renamed the template

Nothing resolved the issue. Any suggestion out there
