How to get G'MOD RP to work

I’ve followd the steps in readme but when i start server i get The LUA BASE GAMEMODE how can i fix this?

Where are you downloading GMOD RP from.

The thread In gamemode realeases on facepunch,

What RP gamemode are you using? DarkRP? Tiramisu? CityLife?

Seems like he might be trying the old GmodRP Script

(Try DarkRP if you want something like GmodRP, I guess)
