Here are some things that could be different and things you don't want to do.
First Caution Point
When downloading the (.PDF) file for the brochure DO NOT attempt to edit the version on your screen.The screen version is still on the Internet. You must download it, let's say to your desktop. It is the desktop version you want to open.
You may get an icon on your desktop that looks something like this, it is still a (.PDF) file BUT you'll want to open it with the Adobe Reader
To open this downloaded file with the Adobe Reader Simply "right-click" on the image and select "Open With" and select the Adobe Reader icon. See below
Second Caution Point
After opening the file with the Adobe Reader and "clicking" on the "SIGN" button at the top right of the screen , you may have a selection arrow to the right of the "Place Signature" selection
If you do have the selection arrow to the right of the "Place Signature" selection click on it and select the "Clear Saved Signature". Doing this will get you back to Step two of the three step procedure.
A third and final screen configuration may appear and it could look like the screen below. If so simply click the selection "Back to "Fill & Sign". Then proceed with step two of the three step procedure.
