Evidently Blogg-X has also been affected by the change in handling passwords that occurred with the Joomla 1.0.13 update. As of now Blogg-X will NOT function correctly with this version because the password hash passed from Blogg-X to Joomla no longer works correctly and can't successfully validate against the Joomla database tables. I am taking a look at the code and will provide an update once I have one available.
