Your arena file hasn't been updated to say 'FRAX Beta 2' and the file name is wrong says 'frax' should be 'frax_b2'.
Nice map. Perhaps too large, alien base would be taken out easily as it would have to be spaced out alot. Dirt texture should maybe be changed and the ground perhaps roughened up a bit more. Also the jump pads should have some marking signifying they are jump pads. Easter Egg? Also your brush work, you stuck the map in a big cube, not a good idea.
