1. If you can find and manually install the 3.19 patch do so. Even if it's already installed it can't hurt to do it twice over (and this is my professional opinion as a programmer) and if not it will make sure you can actually play this mod. 2. If possible delete all possible unnecessary folders. The launcher has issues with moving modules around with very long folder names so any shortening you can make will be welcome to fixing that as windows limits the character count of a full path to 256 characters.
