Steam decided to force update my 9.7 to 12. Ver. 12 on my PC is causing hang ups and lag. Just like ver. 10.
When i run the installer over the top of 12, it does install, then throw a key error.

How do i revert back to 9.7 with my Steam Key ?

Can you send me a screenshot of the error that appears? Running the installer directly overtop of you current install should roll back while maintaining your key

This is the error when installing 9.7 over Steam 12.
Keith was able to provide a work around.
Thank you for your help.

How can solve this? My Steam code is still not working in the old version.

Did you run the installer directly overtop of your current install, or did you uninstall it from Steam first?
