Hi, im new to the whole msql database stuff...but i just set up my zen shop...it all aseemed to install ok....but whenh i try the 2 buttons at the bottom to either goto my shop or the admin area....i get fatal errors when clicking on both

when i try to goto my shop - Fatal error: main() [function.require]: Failed opening required 'includes/application_top.php' (include_path='.:/usr/local/lib/php') in /homepages/9/d189050459/htdocs/zen/index.php on line 26

i get another error when trying to goto the admin area

has any1 had a similar problem??

help would be greatly appreciated as im very new to this type of thing but really need to get to learn it.
