If I restart the server in cc, it comes back after a little time with an error that "Unable to determine if the BF2 server has started."

Something is working because the map changes I made, are in effect on the server despite the error it shows, however there is something missing somewhere.

Edit:  I forgot to change the rcon port in the admin/default.cfg as per the readme  for 1.4.

Quote:
- Note, it is important to set your RCON port, host, and password in the admin/default.cfg provided in order to allow the updater to monitor your server and keep it up to date.

It's fixed and working now.

Just copy the one you already have in mods/2142/settings to mods/FirstStrike/settings .
