Gallery not working after server move

Howdy

I have moved my gallery 2.3 to a new server.

Updated config.php with the new setting
Uploaded all files to my new server (kept the same directory structure)

I get this error when accessing the main.php page ....

Warning: require_once(/home/geordie1/public_html/gallery2/modules/core/classes/Gallery.class) [function.require-once]: failed to open stream: No such file or directory in /home/geordie1/public_html/gallery2/bootstrap.inc on line 33

Fatal error: require_once() [function.require]: Failed opening required '/home/geordie1/public_html/gallery2/modules/core/classes/Gallery.class' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/geordie1/public_html/gallery2/bootstrap.inc on line 33

Any help greatly appreciated !
