maybe use the version that you have to pay for?
I just downloaded the trial of FEX Pro, no dice. Didn't fix anything.
might be time for the snow leopard repair disc
hmm so I can add fonts into FontBook and activate them no problem. FEX and FEX Pro don't work. :(
the old free version of fontexplorer x is definitely not compatible with snow leopard, you've probably borked something.
