I recently downloaded virtual dj, and when installing it, it asked for a serial #. A patches applications came with it, something about "aceCrack". How do I crack the serial #. And everytime I download a zip file, the computers is always unable to open it, how do I open zip files?

You should be warned we cannot talk about wares & illegal copies of programs on the forum for legal reasons. But to open zip files you have many choices such as winzip, winrar, stuffit expander & this one which is very good & is free: http://www.warp2search.net/forums/viewtopic.php?t=4139 Also read the Forum Rules (click here)
