Hey guys, I'm also having a problem with Cod4X.
I've replaced your cod4_lnxded with the original one, then I've set chmod 755, but I can't load it.
Error: error while loading shared libraries: ./cod4_lnxded: unsupported version 512 of Verneed record
I'm using Debian 7.0 x86 btw. Would be great if someone could help me. Thanks
PS: I think I already had it working yesterday, but it said "Key already in use" when I joined, so I changed it back to the original (got same error), now I'm trying it with CoD4X again.
