I have reset my Privacy --> Photos setting but adding an App is not an option

I purchased the Diptic Power Bundle form the App store last week. The Diptic is working fine but both Diptic Video and PDQ are not working. When I start the App, the following message appears:

"To continue, Diptic Video needs to access your photos. Please update your Settings."

I have reset my Privacy --> Photos setting but adding an App is not an option. Running the App again gives the same error message.

I have attempted to email Support@dipticapp.com, message to its FB and Twitter account but have heard nothing back.

Does anyone have a suggestion?

Is this company still in business?

Thanks.
