Hi, The same thing happened to me. Here the way I managed to fix it, though I don't really know why it works: 1. Go to you Skyrim game folder, ussually \Steam\SteamApps\common\Skyrim 2. There you'll find the \enbseries folder, delete it and copy oringinal \enbseries\ folder of your ENB Mod (I use RealVision ENB) 3. Once you have again the original untouched \enbseries folder, start the game 4. On main menu press console (to avoid game keys while playing with ENB menu) and then press shift + return, the ENB menu will show up, don't closed the menu 5. On ENB menu press "Save configuration" Next time you start the game the ENB menu should work, or at least it works for me. I guess than when the menu shows for the first time creates a series of ini files in the enbseries folder, and if you don't save config of ENB y later has some problem to read some ini file or setting and it goes mad... As I said, it works for me, not sure if it will work for you, give it a try and tell me how it goes. :blush:
