I don't how much time i've spent to make this old and fantastic game to work. I'm new to modding, but i'm a fast learner and I hope this question will be answered with a solution in the end. So here goes. After installing fallout 3 GOTY (GOG version) and setting up everything (followed gamepoets "my way" series on youtube), MO would launch Fallout 3 through FOSE, but now the black window opens and then closes and.... nothing. Nothing happen. I go into the task manager and I can see Fallout 3 is running, but there's no window at the bottom to follow. I can launch and play FO3 fine through FOSE without launching FOSE through MO, but the DLC's are not appearing/popping up on the leftside screen (in-game). I tried "deactivating" some of my mods. one of them and multiple! (FSR 4, NVAC, Updated_Unofficial_FO3_Patch and OneTweak) And that didn't work. If you need more information I'll be happy to provide it!!! Just as long I can play this game with all the mods and DLC's working! - REMEMBER! THE GAME HAS WORKED WITH DLC'S THROUGH FOSE IN MO BEFORE!
