EA Strategy Tester not working

 

Hi guys..new to EAs. I am trying to run different EAs in the strategy tester however in my navigator screen, they are grey icons. When I open my meta editor and open the specific EAs, it just shows a few lines of random code. It isn't a typical EA. I am having this problem with all EAs I download from this forum. Am I doing something wrong in the outset? They all appear to be EQ4 files.

Thanks.
