Font Reserve Error Messages


Ive been getting error messages from font reserve often when I load new fonts. -600, -300, etc.

Im on MAC OS 10.3.9....G5 tower, Font Reserve 3.1.3
I have tried to make new databases and start from scratch but after a few dozen fonts loaded, BAMM!, I get the error message.

Also what happens after that, is Font Reserve shuts down and I can't restart it without rebooting my hardrive.

Any help would be really helpful.
