When i try to install 3.00, I do the data pack 4 first and it installs, but then i try to do step 1 and 2 and it says something else is installing and i have to restart my pc to do step 1 and 2. I finally got it to work and i tried to installed step 3.01, and it said again that something else was installing. What can be wrong? Also i got into the game and veltins arena was not there. it was some random arena.
