Thanks! Just one more question, how do i join the iwbums with each other? I am completely new to the modding scene of PZ http://theindiestone.com/forums/index.php/topic/4183-iwbums-the-i-will-backup-my-save-branch/ Follow the instructions here Yeah I found that thread and did what it said, however the problem still remains :/ Hrm... did you reinstall the modelloader after the update to the IWBUMS? Depends what you mean by reinstall, because the model loader comes with the ORGM file as a rar file, however the instructions just stated that you have to extract the ORGM rar file to the mods folder. So I did that but is there something I missed? It didn't state what mods folder I should extract it to so I head ingame and checked the mods section, there it said that mods should be installed on the C: disc, so I assumed thaat I should extract it there in the mods folder. And if you go to the forum post about the model loader the instructions said that you should copy the zombie folder from the rar to the main PZ install directory, however when I do that the game ethier crash or the problem still remains :/
