I received a Low Quality Warning Icon. What does this mean?
This means the resolution on your picture is low and will affect the quality when it’s printed out. Consider editing the picture or using a different one. 

What do I do when I get a Yellow Error Message?
Usually this means you have left a page, picture box or text box empty, but it can also indicate low quality pictures. Just go to the page in question and address the error. This message won’t appear until you perform the “Check Project” function.
