Hi, I'm a newbie in using mods to enhance fallout 3 gameplay. Recently, i have been reading the guides on how to install mods, and have decided to follow wandik's step by step guide to install mods. However, in the course of the installation, everything was fine up until the FOOK installation. My current Fallout does not have any sort of DLC content, so i was skipping any installation related to DLC. I managed to install FOMM, FOSE, BSA, which are the pre-requisites for mod installation, and have updated my fallout version to 1.0.0.15, as well as using the fake patch. However, i encountered branching differences when i began my work. Here is the chronology of my work: First, the Unofficial Patch by quarn, i used the installer version. the version does not show any unofficial esp file in my mod manager, but when i tested it out, it worked fine. at first i installed the DLC contents, but realised my mistake, and chose to reinstall it, skipping the DLC's. As for the fake patch, i used the mod manager's Package Manager utility, and activated it from there, as well as VAT's Fix. Next, after testing out it with FOSE, nothing funny happened so far. But, come FOOK installation, everything became awry. I first tried to install CALIBR using same package manager method, and it comes with CALIBR's merchant .esp. But, when i tested it out again with FOSE, my Fallout starts to crash whenever i open it with FOSE. Unsure of what to do next, i proceeded with installation, with FOOK, at first i used the same package manager, but cancelled midway since there are 3 files which is impossible by using the tool, so i opted manual extraction. I extracted the mods to a separate folder, before copying them correctly to my Fallout directory. I also used FOOK 1.6 esp, which gives me more .esp files. I preceded to arrange them in this manner: Fallout3.esm FakePatch_v1.5.0.22c.ESM CALIBR.esm FOOK.esm CALIBRxMerchant.esp VATSFixOff.esp FOOK.esp FOOK - Tougher Enemies.esp FOOK - No Requirements for Miniguns, Gatlings, 20mm Flak.esp FOOK - Strength Requirements for Miniguns, Gatlings, 20mm Flak.esp FOOK - Additional Power Armor Training.esp FOOK - Reduced Armor Boni.esp FOOK - Test Container.esp FOOK - Free Play After MQ.esp FOOK - Owned!.esp Total active plugins: 15 Total plugins: 15 After that, i tested them again using FOMM, launching FOSE, but it always crashed ( CTD) at the opening credits. I am stuck so far, and i could not figure out any possible solution. I would be grateful if anyone can give me directions on how to solve my current bug. Thanks in advance.
