I can open a pdf tutorial/pattern, or Im getting a message saying that the file is damaged. Whats up with that?
The file isn’t really damaged. Something is happening with your computer. You’ll need to use Adobe Reader to open pdf files. If you’re having trouble, it’s probably because you aren’t running the most current version of Adobe Reader, or your computer’s default settings are trying to open the file in a different program. You can download the latest version of Adobe Reader free from Adobe’s website.
