Howdy Bernie,

I've got version 1.034 installed (I see he has a newer version up which I've downloaded, but not installed yet), and I haven't had any problem opening .mid files.

I have had .mid files that I've downloaded from certain sites that were corrupted. Have you tried opening a file that you know works, perhaps one that you've opened previously in Composer, so you know it's not corrupted?

You might also want to download the latest version of SynthFont, as I know from the past that sometimes he's run into problems in a particular version and had to get out a quick update. Maybe the version you have was one of the problem ones.

ttfn,
Sherry
