Are you sure that the files for your programs arent corrupt?
Can you do a repair install of them?
Anyhow, To quickly view fonts, you can use this, its a trial, but you can run it 10 times before purchase. It wont detect corrupted fonts (not likely you have any corrupted ones anyhow) but you can very quickly view them all (scroll in the bottom box in the main program to see a quick preview of the fonts in wach category)
