I had the same problem. I downloaded the M&B from TW site and installed, and the replaced the .exe file with the one from GoG. Hope this helps.I finally got original M&B running on my newer system a couple of months ago, thanks to GOG. Downloaded and installed Solid & Shade version 26.13d yesterday, which is a bit newer than what I had on my old system a couple of years ago. The mod fired up, but the text on the main menu is unreadable, just a jumble of disconnected black polygons. The graphics look fine otherwise, but I can't play it if I can't read the text. Any ideas?
