Different on different machines - need help asap

[npwtsb]

My client says that:
My monitor shows the Ask the Dealer logo and dummy copy way, way down column 1 instead of anchored just below the purple bar under the nav tower.

He is using a PC and IE...

Altho on different monitors that he uses it looks ok.
I checked it at 800x600 and higher on my monitor and it looks ok.

I cant replicate the problem...
does anyone have any ideas on how to view it or correct it?
I cannot change the table structure much - it was given to me like this...
I cannot make drastic changes.

Here's the link:

1) Web pages are supposed to appear differently on different platforms and browsers. Some people using the web don't even have screens.

2) Tables should not be used purely as a means to layout document content as this may present problems when rendering to non-visual media. Additionally, when used with graphics, these tables may force users to scroll horizontally to view a table designed on a system with a larger display. To minimize these problems, authors should use style sheets to control layout rather than tables.
