VSRO Hamachi SRO Client Problem

hello everyone :)
i have successfully created my private server and i have friends that want to join.

i can successfully load up the sro client on the host machine but when ever my friends launches their client on a different pc, a error msg comes up and the sro clients dissapears.

and i tried this on my other laptop (not the host machine) and same error keeps coming up as it loads up the sro-client. i dont know wots wrong but please help !!!!

If it's a chinese error it can't connect to the server. Make sure Media.pk2 is patched the server host's hamachi ip, and that they connect to right ports. If that doesnt work you should check server.cfg and certification settings for wrong settings.

oh
