rio mp3 player not working

it keeps saying insuficient space to index your content yet i have 1 song on there it also said it when i had all my track on it idk wtf it wrong with it its a rio ce2100 so please i need help

is there a button or option or switch that "locks" the drive. maybe thats preventing you from formating it. If thats not the case, try Call Customer Care

Seems like like a pain just to get someone on phone.
If its under warrenty or if you can still re-turn it to store?
Do it.
