Need help setting up cccam and oscam and installing omnikey 3121

Hi, Can someone please help me set up cccam and oscam and install an omnikey cardman 3121 on ubuntu 11.04, I have been trying for weeks now and just can't understand how to unhash and delete lines. I have been using windows all my life and don't have a clue how to use ubuntu. If someone would be willing to show me how this is done using team viewer i would really appreciate it. Just pm me and i'll give you the details.
