Hi, I have the same problem. - I have hl2, to him, episodes 1 and 2 - Mod installed. Exe and even the second option paste the folder with the compactness I installed the SDK, mod still does not want to start ... What is the problem? Please help Make sure you've also played Episode Two at least once, so it can load all of its caches. I guess something's wrong with my EP2, because no matter how many times I play it, it won't load the caches.
