setting up on localhost???

[treelo]

ive set this up on my localhost machine that is running phpdev and all im getting is the following error when i try and click a link

 

Fatal error: Failed opening required 'includes/languages/.php' (include_path='.;C:/phpdev/php/includes;C:/phpdev/php/class') in c:\phpdev\www\catalog\includes\application_top.php on line 285

 

now line 285 looks like this

 

// include the language translations

require(DIR_WS_LANGUAGES . $language . '.php');

 

so basically its saying the $language is not being brought back

 

BUT

 

when i echo $language it brings back enlgish, whichc is my desired language

 

does anyone know of any similair problems encountered on a locally set up oscommerce?
