Hello Alpha_Charie_SQ3, your in-game username is "Alpha_Charie_SQ3", without the L. It appears that you have applied a license code that you have found on the Internet, and just like you hundreds of others did.
So what is likely happening is that you are getting disconnected when anybody else with the same license connects to any other game server (even not LS, it can be any bf2hub ranked server).
When you try to reconnect, you will disconnect this other player instead, who will also wonder what the heck is going on. He'll try to reconnect and he will disconnect you back, and the loop goes on.
To fix this problem you need to have your own license code applied, so you can do one of three things. Either click on my profile and reinstall the full game with our instructions, or if you don't have the Special Forces expansion pack already we can also give a standalone installation which will also address the licensing problem.
Finally the third option is I can send you a message with just instructions to apply your own code for the game, to avoid collisions with other players who made the same mistake.
First option is 3,2GB download, second option (in case you don have SF and you'd like to have it) is 1GB, third option is a few Megabytes. Let me know which of these you want to try out first and we'll go from there.
Regards,
Staff Officer
