you need to have L-Face and L-Gameplan in your data folder.
you also need liebo.dll and mpeg(something like that) in your data folder and also have the .dll files in your root folder,
make sure that you dont have any of the wils open with gagets viewer( happened to me b4 didnt know what was happening for around 30 mins then rleised i had gadgets viewer was open :P)
hope that helped.
