Thank you! Do you know what version it is compatible with?
I'm not sure, but for the quick read I did, it is compatible with 1.5.2 only. You can try of running in a superior version, it might work, but for a remote possibility. And beware of sites offering this mod updated; some of them just are made to attract traffic making the people believe they have the 1.7.10/1.8 version and then redirect you to the regular 1.5.2 download. Traincraft is a known case. Even worse, some of them make you to download a executable, which contains adware and annoying unwanted search pages and toolbars. If you download one of these programs, delete it and don't run them! Your PC will thank you.
