Supporter changes not saving in premium plugins and premium themes

On the premium plugins page when setting options the button is clicked at the foot of :
and the page directs to:
wp-admin/network/ms-admin.php?page=supporter&tab=plugins... which is where I get the page does not exist error.
There is no ms-admin.php file in the network folder. It is in the wp-admin folder. I am no coder but this does not look correct to me... The same applies to the premium themes options page. It is a problem because the changes do not save.

I have resolved it by revertiing back to supporter version 2.2.2. The issues arise in version 2.2.7
