Downloaded fonts from one macbook to another all I see is AAAAA....

I downloaded from a flashdrive a bunch of fonts from one of my macbooks to the other. A prompt said 50 of these fonts are bad and should not be downloaded. Did not see that until I clicked and it was too late. I have no idea how to fix the problem because all the text on my computer now looks like below.....

I don't have a backup. Should I wipe it? :/

Without additional information, it's difficult to advise you what to do. Tell us which Mac you have and what version of OS X it's running? Reinstalling OS X will restore the fonts.
