Please help, on the chapter that you first meet Drizzd he shows me how to kill the snow trolls. All is fine untill we are told to secour the gate. There, i knock the trolls to the ground but i can't stab them to finish them off. Any ideas? It is deffinately a bug but when i try to install the patch it says "This application has failed to start because binkw32.dll was not found. Re-installing the application may fix this problem"...
