Your client is an invalid version.

PENGALICIOUS

Everytime I open CF and click start on the launcher, the game doesn't load and just says "Your client version is invalid." I've tried reinstalling and it goes back to working for a bit, but then it just happened again.
Anyone got a solution to this?

Thanks in advance.

Edit: OK LOL! I literally just reinstalled right now and this time it doesn't even work once, it just gives me the error again.

Getting the same error.

After, I tried to launch it 5 times, it worked on the 6th time.

Solution: Keep launching CrossFire and it will work eventually.
