Hi Txell.
Are you using Apache? If so, if your server is set up to allow it, try creating an .htaccess file:
php_value post_max_size 64M
php_value upload_max_filesize 64M
Some configuration parameters can also be set at runtime by adding "ini_set()" somewhere (normally Moodle config.php) but I'm not sure if that will work for file upload settings. (I thought I'd used this before, but when I googled to check the syntax a bunch of people were saying it won't work because by the time it runs PHP has already rejected the upload.)
