Can't recognise fonts: Recent upgrade from 10.4 to 10.5, aswell as new computer

Hi,

I work in a small design studio, and we just received new iMacs. My colleague has successfully got his up and running but I am stuck.

We both have the same software, and have downloaded the latest updates.

I transferred my fonts from my old G5 to my new Imac and it is reading them as "Unix Executable files". I transferred them the same way he did, via the network, and it still won't work! I am getting very cranky. Needless to say, I need my fonts!

Is anybody else experiencing this?

I appreciate any advice, cheers
