When leaving the restaurant after talking to Sam, there is suposed to be a cut scene. If you do not see this cut scene while playing then these are the probable reasons:
If playing online, it is likely that your internet connection is too slow and the cutscenes simply have not loaded in yet. If this is the case, I strogly suggest downloading the game and playing from your hard drive instead.
If you are playing a downloaded version of the game and are experiencing the same problem, check to make sure that you have unzipped the file properly. Make sure that both the bounty2.exe file AND cutscenes.swf file are located in the same folder or directory on your hard drive! Both files need to bein the same location for the game to access the cutscenes.
