Cforms2 vs WPML

Hello,
first of all, I want to thank you for the great plugin, it’s my favourite and imho is much better than contact form 7. For example, it’s pretty easy to make translations of input values via WPML plugin without duplicating form.

But from some time if WPML is active and I’m visiting cforms admin, all values of any created form is vanished and it can’t be restored. Just like that, without saving, just clicking into admin. I’m not sure if this is bug of WPML or cforms. Both used plugins are in latest version. Can you investigate this problem please? Thank you very much.
