does this error mean that my Vid driver isn't installed ?

I installed Enemy territory I keep getting this error

Sys_Error: Sys_LoadDll(ui) failed, no corresponding .so file found in fs_homepath or fs_basepath

I am not sure but does that mean that My fglrx video drivers are not installed correctly and that I have to un/re install them?

im a noob but looks for me like you missing a dll maybe dirext?

Need more info how did you install it with wine ore some other way

Please provide glxinfo by typing glxinfo -t in a terminal. Also, do you have other games running? Is it running Natively or in Wine? You have OpenGl installed?
