That'd be why. We don't support DirectX 11 yet. (Support for it in WoW is also in beta stages, so we have no plans to support it any time soon.) Please see the following to resolve the issue: Troubleshooting - Buddy Wiki
alright i didnt find "SET gxApi "D3D11" in the config file or anything similar to that, so i added "SET gxApi "D3D9" to the bottom of the list. i started wow and then started honorbuddy and wow crashed, heres my error log
