For the who dont know how to fix their problem since the update of the game's core engine
If any of you have encountered the problem when opening BoutCheetah and it says "Could not read library: d3dx9_43.dll"
that means you have an old version of DirectX
that's y i made this guide for players because some don't know how to solve this problem and usually stop playing (common thing to do if u don't know how to fix)
Steps on how to fix the error
1. Click this link: http://www.microsoft.com/en-us/download/details.aspx?id=35 (http://www.microsoft.com/en-us/download/details.aspx?id=35)
2. Set the language for the DirectX ( if u don't use English )
3. Click download.
4. After the window appears, just install the DirectX
5. After you installed the update you can restart your pc. (this is optional and if u don't want to do this you don't have to).
6. Open BoutCheetah and see if it worked.
7. Enjoy the game. ;)
That's all.
I made this because i noticed lots of people posted with the same error since the game's core engine update. :)
