No support

Installed original vers. of this app on my 1st gen ipod touch. Recently had a problem loading app so I deleted it and attempted to re-install. Received message that this newer version is not compatible with my iPod touch. I wrote support but have never received an answer. I would not recommend buying an app from a developer that offers no support.
