How's it going folks?

So I've got a question for any of you that might still have the original release of Master Levels for DOOM II. A little while ago I decided to load up my copy of the game (hadn't installed it on this new PC) and ran into a major issue when it came to actually installing it. After being told that the system can't find the directory it needs to find in order to install the wads I decided to take a look at the contents of the disc itself. I click on the "master" directory and low and behold there is exactly nothing on it. No "wads" folder or anything. Is there supposed to be a "wads" folder or possibly a "maps" folder that contains the levels I was trying to install? I'm so damn confused, this disc always installed without a hitch on every other PC but now such isn't the case. Has anyone else had this issue? If so, does anyone know what to do about it? I swear it looks to me like the actual wad files are gone and I have no idea why.

Man oh man, why couldn't Master Levels be released with DOOM 3 BFG Edition?
