Reinstall of corrupt fonts in font book?

Question

I tried researching my issue, but came up with too many different scenarios and also need more specific step by step remedy.
Running Map Book Pro
OS X 10.6.8
Traveling for business and holiday until Jan.
Working in Adobe Cloud, specifically In-Design and Adobe Pro I discovered that certain fonts weren't rendering properly for colleagues.
Online advice said to go to system font book and verify my fonts, then delete corrupt ones.
There were 32. (They are still in my trash, as I was afraid to delete entirely without a restoration remedy.)
So, I can't get to my original install materials, but I also can't work without some of these basic fonts missing for the time being.
How did my fonts get corrupted? (Do I have other issues such as a virus to look for?)
Can I temporarily fix things without the original disks?
Can a Apple Genius do this at a store?
What's the step by step process to fix this for good?
Any recommendation or help appreciated!

Answer 1

Should I put back the fonts i removed  to my trash can back first?
In case any of them actually are bad, no. Not that it would matter if you did, since retrieving them from your OS X install disk as outlined in the article will replace all of them with fresh copies anyway.
Do these steps in the order shown.
1) Follow the article's instructions to reinstall all of the fonts in the  /System/Library/, and /Library/Fonts/ folders. This will replace all fonts with fresh copies from the DVD.
2) Reset Font Book. Restart your Mac and immediately hold down the Shift key when you hear the startup chime to boot into Safe Mode. Keep holding the Shift key until you see a progress bar towards the bottom of the screen. You can let go of the Shift key at that point.
OS X asks you to log in (you will get this screen on a Safe Mode boot even if your Mac is set to automatically log in). Let the Mac finish booting to the desktop and then restart normally. This will clear Font Book's database and the cache files of the user account you logged into in Safe Mode.
3) Since step two does not clear the system font cache files, you need to do this next.
Close all running applications. From an administrator account, open the Terminal app and enter the following command. You can also copy/paste it from here into the Terminal window:
sudo atsutil databases -remove
Terminal will then ask for your admin password. As you type, it will not show anything, so be sure to enter it correctly.
This removes all font cache files. Both for the system and the current user font cache files. After running the command, close Terminal and immediately restart your Mac.
That's it, you will have all known good copies of your fonts, and newly created font cache data. At this point, if you always use only the fonts supplied with OS X and don't ever add, remove or manage your fonts (turn them and or off), there's no need for you to ever launch Font Book. Heck, you could throw the app in the trash if you wanted to (but don't in case you need it at some point).
