[SOLVED] sandbox system

I have problem with sandbox mode. When I try to do anything It says only that player to open g_sandbox...blah blah. Nothing going to hapen. I can't even open sandbox help- it also says that player tried to open g_sandbox help (or something like that). I tried several servers, single campaign mode, own room etc. How to use this system?

Afaik, there aren't any servers that allow you to enable it, but g_sandbox 1 will enable the sandbox mode in local matches. Also, to delete any changes that you've made with the sandbox mode, delete the files in the directory 'data\sandbox\'.
