" What am I not getting right? It was working on the previous load"
- Previous load (installation ? ) of what, the OS, the game, or both ?
It's impossible to tell what you may not have right, you didn't give much information.
There are a number of potential sources for you error message.
- Have you installed or removed any mods ?
By 'load', if you are referring to a game save, try using an earlier save. The most recent save may be corrupt. Saves do get corrupted at times with Bethesda games. The potential is greater if you
remove a mod, or mods.
- If you reinstalled the game after using mods did you delete any folders that may have
not been uninstalled (such as the Data folder with the mods) before reinstalling ?
Are you using the same game saves and .ini files from the previous install ?
- Are you using multiple monitors ?
- Which graphics card, and which driver version are you using ?
If you have reinstalled Windows -
Have you updated DirectX ? -
Download DirectX End-User Runtime Web Installer from Official Microsoft Download Center
Have you installed the 'important' Windows Updates ?
- If DX, drivers and Windows updates have been done and there seems to be an issue relating
to Steam you should post on the Steam forums.
