something happened and mods wouldnt work so i decided to unistall delete the data folder and reinstall so i can reinstall mods but after i updated the game and started it no mods the game crashe but everytime it was when the mouse cursor came up on second slide

Could be...

A) Missing masterfile(s). FO3Edit will point you to missing masters with its "Messages" tab when loading your mod list.

B) Sometimes, after reinstalling/patching, certain values in Fallout.ini can cause a crash during the slideshow. FO3 will create a new .ini in the event the old one is deleted or renamed.


Tending to A, B, or both should get you up and running.

thank you A helped
