Thanks for your help! I realised that I had to wipe Vortex and start from scratch. Again! But Hey! at least I unearthed some mistakes I made ... So I stumbled across a guide - CBM-guide - and I guess it´s profound and reliable, seriously! I checked every step I took, and then again to make sure I get it right ... But I got to step 3 (for crying out loud!) until the next error hit. I downloaded the dll plugin loader and followed the instructions closely: 1. Go to your Skyrim Special Edition root directory. This is the same folder where SkyrimSE.exe is, usually "C:\Program Files (x86)\Steam\steamapps\common\Skyrim Special Edition\" 2. Rename "binkw64.dll" to "binkw64_.dll" <- now there's a _ at the end. 3. Put the "binkw64.dll" from downloaded archive into the folder mentioned in step 1. 4. If you did it correctly you should have two files in your folder now: "binkw64.dll" and "binkw64_.dll", that's all, you can start the game now. Edit: The SKSE and the Adress Library at least are right this time, I checked XDDD Then I started the game (intended to) and the followin message appeared: "Failed to load binkw64_.dll! Make sure the original file exists with an underscore at the end of name." I do have the two afforementioned files in the right folder. Thanks for your patience, if you could help me along any further I would be very grateful. Edit: At least the SKSE and the Address Library are right this time, I checked XDDD
