after the lastest update (6.4) i replaced old template_6 folder with new one, but nothing works.Everytime i try to start a level, tons of script errors comes up, even a simple level with 1 model and one cube as the group. i put the action Blpied01 on a model and tons of script errors, here are some:

<my._step_height_003==0>

<BipedSnd01_Update_Loop();>
plBiped01.wdl 367:0 Error(29): Keyword unknown BipedAnim01_Update_Loop

Is all those errors normal, or did I incorrectly update my 6.11 Extra, if so, how should i update it the right way?
