Urgent check with this site please - works ok. but not everyone

Dear friends.
Can someone check this: www.ossianguesthouse.co.uk
It is an html page with a swf at the top for sound
and the main movie (main_flash.swf) that loads other
swf’s via buttons.

Using Flash 8 - but published swf’s for version 7

some people say they only see The Ossian guesthouse words
dark dreen bckgroun- a picture loaded but not
the text swf’s. and no buttons - particulary people from Ireland??

Any thoughts on this -
Have asked many friends with different browsers and mac’s etc
and 99 said ok.

Appreciate any help asap as its live now.
