I've tried to come to mapping for the first time, I found out I don't have all content needed just TF2 and G-Mod. So I decided to get THIS tool. When I tried unzipping and then running as administrator, it didn't start. Tried changing file options - didn't work. Tried properties - same...

I really want to do some mapping without errors everywhere or missing textures. Please respond and help me! There is one topic about it that is not answered yet.
