Came back to the game last night after a 4 month absence and found I could no longer play. Long story cut short, I've updated everything as per post title but when I run SKSE launcher I get the following... [11 May 2019 14:10:33.429] Initializing framework version 7. [11 May 2019 14:10:33.433] Loaded configuration file. [11 May 2019 14:10:33.435] Preparing .NET code hooking. [11 May 2019 14:10:33.440] Loading game library. [11 May 2019 14:10:33.550] Loaded game library for `The Elder Scrolls V: Skyrim Special Edition` (9). [11 May 2019 14:10:33.551] Running game version is 1.5.73.0 [11 May 2019 14:10:33.561] (InvalidOperationException): "Game library `The Elder Scrolls V: Skyrim Special Edition` (9) does not support game version 1.5.73.0!" at Now SKSE homepage specifically says - Current SE build 2.0.15 (runtime 1.5.73): I checked game and it is indeed 1.5.73.0 I've re-checked correct SKSE install including pex files Loot is reporting no issues other then ITM reminders about deep cleaning I'm bemused. Any input anyone? Please and thank you.
