Hi Deathsangel, Do a clean install of the vanilla JA2, you can also do a file copy of an install, it'll work as well. Then extract the 1.13 into the same directory. Kaerar has a one click install of the latest SVN if you want to play the latest version. You can also extract into a separate directory and then do a file copy, just make sure you overwrite the existing files if asked to.
