are these PSD that you created or are they from another source? a lot of times PS will create a file and save it okay even though some font info is corrupted. Then when you open the file on another sys it throws up this error. (even though on some systems it opens just fine!!) - but like i said Adobe had fixed this awhile back...

anyway, there was a droplet Adobe posted the let you "drop" the file on and it would correct/fix the issue. not sure if it's still around...

i'll look around.
