Isarli, if there are no other issues with the iPod, if it did not get dropped or otherwise damaged, I'd try a complete reset and restore (make sure that you have all your files backed up and that you have a firewire to complete the restore process). If that does not help I think it may be time to replace your click wheel. Not terribly expensive and relative easy to do. Follow this guide all the way through. Once you have the logic board removed you will see the click wheel. It is glued to the housing and you will have to pry a bit to get it off. I usually do not use any additional glue when I place the new click wheel. The residual glue is enough to keep it in place. Let us know if you need more help wit it. Good Luck
