im no expert with wine but you need to set it up even though its installed. do you have wine in your kde/gnome menu? if so try runing that and wine will guide you through the steps to setting it up. you can either have it use your existing windows partition or it will create a fake windows partition on your *nix drive.
after its set up you can try installing a certain windows app by opening the command line and run:
just put "wine" before the command to install but remember it works, but needs tinkering.
as someone posted, frankscorner.org helped me install kazaa lite and nero on linux a few months back. HTH
