To make life super easy for players, OJP uses an installer to install the mod - InstallOJPEnhanced.exe
If you look at some of the recent threads here though, OJP was taken down because we caught some bugs that need fixing. Thanks to the JK3Files staff, the bugged OJP release was taken down so that the problems can be patched up. Don't worry, you'll get your hands on a less buggy version very soon. Darth's been working hard and definitely deserves a break following release, and everyone beta testing and hunting for bugs has made the process so much faster.
