"Fatal Error: Language Database File xxxx.dat not found" This error occurs when trying to launch any FRx Reporter application. The name of the file may vary, but it will always end with a DAT extension.
The specified DAT file is missing from the FRx directory.
Any of the following fixes may be used: Copy the appropriate DAT file from a working machine. This is only valid if FRx is installed locally on each workstation (a fat client setup). Restore the FRx directory from a backup. This may apply in either situation (local/fat client or network/thin client setup). If FRx files reside on the server, and no backup of the files exists, FRx should be re-installed from the FRx CD into the same directory. After installation, be sure to re-apply the latest FRx service pack to ensure that all files are up-to-date.
