Can't get LFH sim Scripts to load properly: a ex4/MQ4 issue?

I'm trying to set up LFH simulator on MT4 and can't get the scripts to load correctly. They'll all grayed out. see pic. I think it's because the simulator download only gives you ex4 files but you also need the MQ4 files in the same directory and they aren't supplied. or maybe that's not the problem at all. can someone help?

Can't. I meant can't in the title. Sheesh.
