Yes sorry for the lateness but it was needed as we encountered major problems and bugs (amongst some that are inherent to the game and GTV !) but now everything should work flawlessly.
As for the textures, we use the RN Q3 textures replacement pack with colors. There is a much better one with real textures (again from RN), but you'll have to download hundred of MO instead of only some KB with the current pack.
As you want guys, if you badly want it we can maybe do a vote ?
