I've given up helping people fix their broken games. 98% of the fixes have included fixing an improper installation and/or having the person update their game/mods. I have literally given up fixing games because of this, because then they want a step-by-step walkthrough to installing peds, cars, liveries, etc. Like no, if you can't handle downloading the most up to date version of a plugin and literally drag and dropping it into your directory, you don't deserve the more complicated stuff. Harsh, but true.
I've left this list untouched because by now, most everything (especially the major, popular plugins) are updated and working for 0.4/0.4.1. This thread was made literally hours after the release of 0.4.
