Formatting, pdf, and SP2

I have a strange issue that I need help resolving. Basically, the formatting
on a report that I am exporting to pdf changed when I updated my VS to the
SP2 of the Reporting Services. Here's what I am trying to do and what SP2 did:
I have a report that I created that makes address labels. I made it to where
it has three columns, and it fit 10 rows on one page. It worked great, until
I installed SP2. Now, it will only print three across the top of the page,
then move on to the next page.
So, my questions are: 1) should I reinstall pre-SP2 RS so that I can do this
report the way that I had it, or 2) does anyone know of an example that will
help me to do what I had done in the pre-SP2 installation?
Any help would be greatly appreciated!!!It sounds weird, and at least I don't know if this is either caused by the
SP2. But what you can do is redefine your report's margins
