My iHome won't play music or charge my iPod touch 3rd gen?

What should I do? I already updated iTunes, I restarted my iPod, I unplugged my iHome for a while and then plugged it in again and tried again. It still won't work!! The weirdest thing is that it was working earlier this morning, and I came back tonight and it wouldn't charge or play music. Is there something wrong with connectors? Should I bring it back? (Keep in mind I'm not really a tech person...) Thank you SO much for taking the time to read this and answering... I really need help! ;)
