How can you remove write protection from a cd?

I have a cd that i got for free somewhere to try out a free program. I want to use it to put files on but if i try to it says it is write protected. Is there any way to remove this

It's more that likely they used a read-only CD. This means it's not rewritable and you can only use it once (as they did). Sorry

as james said unless its says re-writeable on the cd or RW, then you can only burn it once unfortunately !
