I don't want to be insulting, but I can't put your map on my server as is - it plays nice (well, for up to four players), but visually... you might want to use evil2_basefloor/flr_tmtl instead of toxic/toxic_grate so it doesn't cause so much eye strain... evil2_basefloor/flr_tmtl looks in game more like toxic/toxic_grate looks in the map editor, which I assume shows what you REALLY wanted.
It would then look like this:
Oh, and you also need to put some light entities and compile with lighting. You see the dark areas on my screenshot? I compiled with lighting, but there aren't enough lights yet for a map of this type.
HTH
