MC Logo out of place

Hi all,m
Im having a weird problem with me Flash site, I got a logo within a MC that seems to appear out of place with Internet Explorer.

I had to place the MC more to the left of the actual place that I want it to appear so that after exporting the .fla to .swf it would appear fine (I know, a messy solution will lead to messy results). Now when O upload to the server, some visitors are seeing it out of place.

Can anyone see this error, and any ideas on why it is happening? the site is http://www.brazilianprofessionals.org/ the logo in on Top left (Brazil flag, with white circle and words). Many thanks!
