- Navigate to the Skyrim folder (\Steam\steamapps\common\skyrim)
- Right-Click the Skyrim folder and choose Properties
- Click the Previous Versions tab
- Find version of the folder from before today, highlight it and click Open
- Copy the TESV.exe file and paste it into your game directory
You might want to keep an extra copy of the original exe in case it gets over-written again.
Happy hunting! And I'll thank you to keep the Bethesda bashing out of my thread. You can post that crap in any of the other threads.
