So I uninstalled Enderal, but I attempted to back it up instead of delete it.
It was truly the exact same issue, so I was happy to see that someone else had solved it. The installation worked fine, but after I started the game through the launcher, I got the exact same issue as this guy: My Skyrim game was heavily modded before that, but I did use Nexus Mod Manager to uninstall all mods before I installed Enderal. I was looking for a new experience, so I decided I would give this cool sounding mod a shot. I'm not entirely sure the etiquette for this, but I'll do my best.
