Emutron, we are going to need more information than what you have given us. As Betamax stated, what error message are you getting? How about also giving us your computer specs, SPU plugin, CD rom plugin, and which version of Pete's plugins you are using. Also what video card you have could tell a lot. For instance, if you are trying to use a Voodoo card w/Pete's plugins, then it may not work too well. If you give us more information we can help you better.
