Make a backup copy of your current FsP database, put it in a safe place. Uninstall FsP, reboot pc and then re-start FSX. If it functions properly, re-install FsP, reboot pc and re-start FSX-SE and see if the issue arises again. If the error doesn't come back, delete the new database folder, copy the saved one into the main FsP folder so you won't lose company progress. However, if the error comes back, maybe Dan will need to do a small update for compatibility reasons. If you are getting the error after a -SE update, possibly others will, too.
