Joomla Templates

Hi ! I still have got the same pb. I m working on an I-mac, with leopard.
I download templates from joomlaos.de, or else, and most of them are not modifiable. why ? <what can I do to change that ? for exemple, I'd like to use the: tc-wings15, beprofessional, and 247fajka.

Is there anybody who use them and can send me ? :unsure:

Thanks for your reply.

I also whant to thanks Lachlan, who helped me a lot last time !
