This error message is returned by System Manager and is described in the error messages section of the System Manager manual. It means that the XXLRSC.xxx file in your data directory may be damaged or you do not have the correct rights.

Rename the file QRLRSC.xxx (where xxx represents your data extension). The file will be recreated.

Renaming the Resource file will not affect your report file. Please make sure that it was the only file that was renamed.

If you are using WSM 7.0, you will need to upgrade QR to the 65A release. You will also need to upgrade for Y2K compliance.
