a smazat tech 7 souboru co jsem psal a pak preinstalovat DX9 jsi zkousel?!

If you silly like me and did not have restore point to uninstall dx10 you will need to search the windows/system32 for the following files and delete them.
d3d10.dll
d3dx10_33.dll
d3dx10d_33.dll
Nucleus.dll
d3dx10.dll
d3dx10d.dll
dxgi.dll
Install DX9(c) after you done. Reboot.
