Unreal 4 auto install won't start on Yosemite

Hey guys, I’m fairly new here so sorry if the questions a repeat of an old one.

got unreal 4 on my mac side because I recently heard that people were saying Unreal 4 runs well on the new Yosemite Mac OS. I downloaded the Epic launcher and it logs in fine, as well as saying it downloads fine, but I had a problem where the internet kept cutting out when I was downloading the actual unreal 4 engine; now the unreal 4 instal won’t start on it’s own, but just stays greyed out saying it’s “not installed”. I’ve deleted any previous files from the attempted download, re-downloaded and reinstalled the launcher, restarted the computer, and so far it’s been for naught. If any of you have had this problem please! You’re help would be appreciated!

Nevermind, did some more research and found out the source of the problem.

Quite embarrassingly I have to admit that all I needed to do was to hit the resume button in the library…hahaha

Wow thanks, I was really stumped on this too.
