So after a patch, you cannot run the DX9 version at all? Even through the Windows Start menu?
When the patch is finished, does it say it was successful?
What happens when you try to launch the game from the Windows Start menu, or Desktop ICON, or directly through the Windows File Explorer?
No. The first download of 19 I saw an error go by in the install, then I was met with the Initialization failed with -9 mainWLD_FAILED -1, upon trying to run the game.
Then I immediately tried to over install my last download which was 16, after that I can't tell you much of what, how or why I did what.

I downloaded the latest game file and went to bed, complete uninstall and reinstall this morning and working fine now, thankfully this time I had all my settings, skins and terrains saved.
