Jac0b, i had a similar problem that i solved a few hours ago, i even made a post for help but, i kinda solved it myself. Try to update your windows and/or your NET Framework, which i believed was my problem. Since a very long time ago(few weeks), my Windows update was having a error (8070422 was the error), and it wasn't updating, so a lot of problems started to occour on my computer, and i knew it was related to my ENB problems, call it a hunch, and i was right.
If you having a similar problem with your windows update, i might be usefull to you, so, if you need just ask, since i came across a ton of solutions for many windows update related errors.
If that isn't your case, try to update your drivers, directx, and one solution for some other games that i had trouble with enbs, copy your d3d9.dll to your sys32 folder, and replace if you have to, JUST DON'T FORGET TO MAKE A BACKUP OF THE FILE THAT IS GOING TO BE REPLACED!!!!.
Those are the solutions to most problems you'll encouter, if any of this works, try to download and reinstall the ENBs presets, and aways looking for any corrupted files if you don't use a manager for downloading. I hope that this helps you out, i know how this things are annoying.
