So I needed to download a new version of F4SE, the updated one, and I wasn't paying attention when I typed it in really fast and clicked download and dragged all the files in Fallout 4's file. I think popped up saying that it had to overwrite over three hundred other files. I clicked yes because it was F4SE and than my Fallout 4 wouldn't open. Even the base game launcher wouldn't open, I remembered that the version of F4SE was old and not the correct one and when I went back on the website it was updated to the correct F4SE. I re-installed Fallout 4 and deleted all of the F4SE that I could find but it still didn't work. I than downloaded the newest version of F4SE and it still doesn't open. What happened?

I recently got my Fallout 3 to work on my computer because I have Windows 10. I started playing it and obviously I wanted to mod it so I begun to and none of the mods worked! Textures, Weapons, Armor, Etc. I checked that I needed everything I have Fallout Script Extender, ArchiveInvalidation Invalidated and all the mods needed extra mods and it never works! I re-scanned my games that didn't work so I manually found the files for Nexus Mod Manager and it still didn't work. Every time I opened the game it crashed too! Then I started downloading the mods manually and it finally work with some mods. Iron-sights kinda work but the gun is pushed all the way up so I cant see the enemy, and the textures don't work! Is this something to do because of my Windows being Windows 10? Or am I doing something wrong.
