Exporting PDF to Powerpoint results in skewed formatting in the powerpoint

In Acrobat XI, when I export the PDF to powerpoint, everything shifts on the resulting powerpoint slide to the left. When I check the Page Setup, it is set to A4. The original PDF is set to letter size, the fonts are all coming across the same, so the page size is the only thing I can find that would affect the Powerpoint output.

I tested this procedure on a different computer running Windows 7 using a trial version of Acrobat XI, and it worked fine. Now I have downloaded the update to TCS 4 that includes Acrobat XI to a new computer running Windows 7, and all the slides are coming in with text and graphics and headers/footers shifted to the left.

Any suggestions?

thanks
