for some reason our computer will not read pdf files any more, we have the adobe program installed still, but i cannot look at any files or e-mails that are sent to me in pdf. i have a bad feeling that i might have touched a wrong button and that has caused this problem, any help would be much appreciated. Mike

Try updating it to the latest version,if that doesn't work you may have to uninstall then reinstall the latest version of adobe.

all fixed, turns out the wife changed the security settings on the computer and that was the issue.
