my game wont start v84

i try opening intruder and it is stuck on the pre-login screen. it says loading..., a percent with no number next to it, the version of the game with no number next to it, and a ... under the loading bar. they game wont get past this. i have trying getting rid of intruder and re-downloading the zip. tried restarting, got it past it once and couldn't do it again. i have been tinkering with the map maker so i am led to believe that unity or something has screwed with the game. the chat and forum buttons do not work as well as the quit button. I attached the image of what the problem is. help if you can.
