If you are using a cracked copy then this could cause a number of problems with your system which would be difficult, if not impossible to resolve. It will help to provide you with updates and support.
If you are using VDJ7 pro then I would suggest you register this software on the forum. I can't help you with the EQ issue unless you post very clear information as to how you have set your software configuration. Normaly this just needs the LINE IN volume turned up on your computer soundcards mixer.
It is possible to take a feed from the output sockets on the BCD, feed this into the LINE IN jack on your computer and then set your computers sound card to output the LINE IN signal from your speakers. As far as I am aware the BCD3000 contains its own sound card which already provides a seperate HP cue and mix output so there is no need to use the sound card on your computer.
