Need help with installing the realm pls

I unzip the files into my d2 folder, then it starts getting errors and wont load up the game, also i don't know where to get G.W.E

your gonna want to make a fresh install then unzip the d2bm folder contents into it.
this realm is version .10 so if your trying to go on bnet with same folder as d2bm then its gonna get patched and cause errors.. make sure your using 2 seperate folders. you can get gwe off google.. just google "bnet gateway editor"
