OpenPDC data archive failing

Hello All,
Our OpenPDC stopped archiving in June. The LED in the top right of OpenPDC is red and historian has stopped working as well. I tried restarting the service but I get the following error" The openPDC service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."

Here is the error report from OpenPDC:

Maybe my archive files got corrupted.

Thanks for your assistance!

Best Regards,

Try stopping the service and renaming the Archive and Statistics subfolder in the openPDC installation folder to ArchiveOld and StatsticsOld, respectively, then restart the openPDC service.

If this is an archive corruption issue the service should now start.

If the service still does not start - there may be a settings or configuration issue.

Thanks,
Ritchie

I tried this and the service will still not start. I also deleted these files: ppa_archive.d
ppa_dbase.dat2
ppa_startup.dat
scratch.dat
