Default Voice Pack

I installed a voice pack but I don't really like it. As usual it's a bunch of funny clips that, to me, don't obviously relate to the actual achievement.

Anyway how do I go back to the default? The only way I can figure is to individually set every achievement to default. I'd rather uninstall and reinstall the program than do that.

under voice pack configuration go to file -> new. That should reload all defaults.

Ok, I'll try that when I get home. I saw the option yesterday but I was afraid it would set all the call outs to undefined blanks instead.
