Re: DirectX error

First of all, your 13.1 driver is old, very old and your new graphics card will benefit from an update:

http://support.amd.com/us/gpudownload/Pages/index.aspx for download of that

If the above does not fix your system I would try reinstalling DirectX. http://www.microsoft.com/en-us/download/details.aspx?id=35 has the installer.
