OK, you have told us of your frustration, but not the details of your problem :)
Can you provide the following information please?
1. Which template you are trying to use.
2. Which size labels you are using (the Avery code will be fine)
3. Which printer you are using
4. The size of the top, bottom left and right margins on the page setup dialogue box (once the template is loaded)
5. Whether the misalignment is horizontal, vertical, or both
6. Whether your printer default paper size is set to A4 or Legal (in Start > Printers & Faxes > Properties)
7. Whether you have WorksSuite or Office installed (or both), and which versions
