Unable to load Unreal Tournament project from latest release branch

Hi everyone,

I am fairly new to all the Unreal stuff.
I am using the release branch for Unreal Engine from github. It was build from source on my Linux system today. When I run it it says its version is 4.11.2-0+UE4. Then I downloaded the Unreal Tournament project from release branch on github. Since they are both release branches I assumed I should be able to load Unreal Tournament project in Unreal Engine. It says that there is a version mismatch(unfortunately it does not specify which exact versions do not match)… Then I press “Open a Copy”. After that I get following message:

Project files could not be generated. Log output:

P.S. I would try UE 4.12 to see if I get a different result, but that version of the Engine just fails to start at 35% with an error compiling a shader…
