You don't need that .lst file. But you do need .pfb and .pfm files to go along with the .afm file (the pfb and pfm files have the same name as the .afm file). Place them in the same folder, then right-click the .pfm file and select Install. (In fact, you don't need the .afm file on Windows.)
Thanks for the reply. The other files I got with the .afm's and .lst's were very small files, not even 1KB, compared to the 16KB .afm's. I think the files she's given me haven't been exported properly/all the data isn't there.
Anyway, thanks again for the help. I'll be able to keep what you've said in mind for any other issues.
There's a very good chance those are Mac T1 fonts, and are totally useless on Windows.
I've been thinking that because my teacher is a notorious pro-Mac user. I guess I'll just grab a hold of a Mac for a while and see whether those fonts will be suitable, and if so, find a converter of some sort.
