WPML 4.4.5 compatibility issue

Hi, nice plugin. Exactly what I was looking for.
At the newest WPML Version 4.4.5 (updating from 4.4.4) I got following error (@1.0.5):
Fatal error: Uncaught Error: Call to a member function add_service() on null in /wp-content/plugins/advanced-exchange-rates/includes/class-advanced-exchange-rates.php:196 Stack trace: #0 /wp-includes/class-wp-hook.php(287): Advanced_Exchange_Rates->add_exchange_rate_services(”) #1 /wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #2 /wp-includes/plugin.php(478): WP_Hook->do_action(Array) #3 /wp-settings.php(546): do_action(‘init’) #4 /wp-config.php(111): require_once(‘/home/httpd/vho…’) #5 /wp-load.php(37): require_once(‘/home/httpd/vho…’) #6 /wp-blog-header.php(13): require_once(‘/home/httpd/vho…’) in /wp-content/plugins/advanced-exchange-rates/includes/class-advanced-exchange-rates.php on line 196
