you should probably provide a little more information for a good answer. Like:

what mod(s) do you have active?

Have you tried restore backups in Mod manager?

If no mod(s), have you tried reinstalling freelancer?

If you do use mods, have you tried reinstalling freelancer, the mod, and (maybe) FLMM?

The more information you provide, the better and quicker your answers will be.

I have heard that sometimes old character files for the server can be the cause. I suppose they are located where you save games folder is (use FLMM to find that), then if you go out of hte save games, am sure the server save characters from players is there. Delete all of those as well, then try again. Another thing is, do a fresh intall, you might have a file missing somewhere!

ok , ive searched for all the server stuff and deleted it , it works again.
thanx
