I have set my .cgi files to open with notepad and I can edit it in the launcher, but setting ANY MODS and I mean ANY, the splash screen comes up and then will crash. I set the mods from "on" to "off", when that did not work, I kept it blank after the "=", but it did not work either. I use the .jar version of the launcher and use OS Windows XP 2000 Home Edition.
