Events+ and WPML: 404 error for translated events

I've recently installed Events+ plugin on my WP 3.4.2 site using 2 languages. The events created with the Events+ plugin are translated from language 1 into language 2 with the WPML plugin. It is however impossible to view the translated event in the front end - I always get the 404 error.
Could you please help me with this issue?
