[Plugin: WP-Filebase Download Manager] Emptying css cache, how to?

Hello,

I’ld like to empty the css cache of wp-filebase/wp-filebase.css and I don’t know how to do it.

I tried to edit the wp-filebase/wp-filebase_css.php which is called and perform the css cache and display… but I don’t know what to do with it to empty the cache.

Thanks for help.
