On WordPress MS doesn't work anymore

Hello,
since the last update, the plugin doesn’t work anymore (it doesn’t appear when you edit a widget).

I used it until the latest version 1.0.1 when stopped working.

I use it under a WordPress MultiSite installation and the plugin is activated in the whole network (not in every blog, active as default in the entire network).

Could the problem be related to the new WPML activation check? Because WPML is active in the whole network too (not manually activated in every blog).

Thanks in advance for your help!
