More Tag protection not working for me in Protect Content

The more tag is not working for me since installing the very latest update of Protect Content on http://www.engagedinart.com. I rely on this method heavily for portfolio items so that visitors can see a "teaser" but not actually see the download link until they subscribe. It was working before and I have "hovered over "read more" content option to see the Modify Access link where I added my access levels. I have wasted a whole day trying to get this to work unless I am not doing something properly. I tried a generic theme and disabling some plugins but this did not solve the problem. I would love to get this working. Any ideas please?
Thank you, Lesley
