amnesia install problems

[vando23]

Hi, so i am having some problems with installing the game through steam.
Below is a message i sent to steam which told me it wasnt there problem and to contact here.

"I am having problems with my purchase of amnesia the dark descent on the mac.
Originally when i bought it a few weeks ago and installed it it was working fine, then a week ago when i went to play it again it started playing up, it took forever to get started and then steam crashed, when i went to play again it said there was an update for it which never showed up or started in my downloads, and when i clicked play, it said the servers were busy. So now it says its downloading an update even though nothing is showing up and whenever i click play (ive tried this for over a week now) it says servers busy. So today i deleted local content and tried to reinstall which still tells me servers are still busy."

Its been about 3 weeks now and no luck and no help. Im not sure what the problem could be.
