I updated it to 1.02 then when I go to 1.3 it says there's a file or more missing... So, I would greatly appreciate it if anyone could help me. Thank You.

I saw your post Sunday, and was hoping someone might be able to help, but since we use Lock-On, this might not be the place to find help with Falcon.
Not really sure where to send you, except Viperpits.org - my friends over there all use Falcon...

Check out the link:

See communications menu on the left side. Then select comms setup for information to join their teamspeak server. Someone should be able to help you there.

They fly allied force and open falcon.

I am a little late but if there is an error saying something is missing you are best off un-installing your install. Chances are you made a modification and the patch doesn't like it and refuses to continue.

You need any more assistance you can check out Lead Pursuits site:
