Did you check this list:
[Only registered and activated users can see links. Click Here To Register...]
have you googled your error code, yet?

i have this massage
Fail to update protection modules! - Error code [0x3000001 c)
i found this problem only when did the last update

You could check the Nexon forum as well, there could be other players with exactly the same problem. I've never seen an error like that, so I can only support you with my tipps :)

1. You must deinstall your Combat Arms!
2. Then download CCleaner and clean your registry. I hope you know how it works.
3. Now install Combat Arms again and play.

Enjoy!

I hope i could help you.
