Oviscity Help

I recently got the oviscity map and the fix script but how do you get money in it? When you go to shops you have to buy things and i dont know how to get money, also it says im not authorized to get into the combine hq and at the gunshop it says “I only sell to legal citizens”.

P.S.- When I go to multiplayer in garrysmod no servers come up.

(EDIT)-Okay I know the part about Oviscity is scaring people off can someone at least tell me why no servers are coming up?
