First, Erminig development isn't related to GPE Suite development other than the fact that Erminig syncs GPE Calendar and Google Calendar.

Second, David Hautbois was the originator of Erminig, but he passed off development to Pascal Jermini. Read more about it here:

Erminig has had issues ever since the last release (in October 2008). Try contacting Pascal to see if he has any word.
