Thanks for your help and I'll kepp what you have said in mind.
There are just two things that I am still uncertain about.
(I am very cautious of what I do at the moment becuase I have only realised yesterday that I have been scamed by a company that offers Limewire, so I do appolagise.)

But...
1.) If I am unaware that a file I download is copyrighetd and get caught am I still liable to pay a fine or in worse case senario go to prison?

2.) Are all downlaods that are TV programs (say the simpsons) copyrighted, or could it OK to download things like that?

Thanks a bunch.
