ADE does not recognize my Samsung Galaxy Tab Samsung SM-T310

I'm using Windows Vista, I updated ADE today, but when I run it, there is no device. Calibre sees my device just fine, and so does Windows Explorer.

Because of this, I cannot view or read the books I borrow from the public library.  (I don't use ADE to read, I don't read on the laptop (really really not an option for visual comfort reasons)). I just want to read the library books on my tab, so if there is a work around, would love to know, as I suspect my device is not supported, yes I checked the blog, and there is a generic listing on the 'supported devices' page,  Samsung Electronics co. LTD eBook Reader on Galaxy Tab Android

Thanks for reading,

Ingrid
