Interesting update issue today. Your plugin has started showing up in the plugin updates list in WP Admin today. It says:
WooCommerce Menu Cart Pro You have version 1.5.2 installed. Update to 2.5.2
But when I click update, it goes through the update process without any problems, but then still shows the above update message! Could it be that there is an problem with the version numbers in the files somewhere? I've tried updating a few times now, it all seems to have worked fine, but then continues to give the update available alert.
Any ideas? Cheers, James
