I tried new games on the 0.9 and 0.11 compressed versions and URM doesn't work on new games created there either. There's a 0.5 uncompressed version near the start of the thread that works though, in case anyone else is interested in working around the issue. The save won't work if it's right at the start of the game, but if you skip to the first choice and save there it loads fine in 0.13.2 and runs URM.
