How do I protect my iPod Touch applications and photos after I lost the host computer?

Here is the problem.

When I bought my iPod Touch I registered it to a computer. When I try to plug it into a different computer, it warns me that I will lose all my applications if I switch computers. The original computer that I registered my iPod to no longer exists so I need a new host computer.

I do not want to lose the information on my iPod, they are too important. How can I change computers without losing the info on my iPod?

Thank you.
