I have installed Comic Rack on my Desktop along with a few comics from their site. I'm trying, unsuccessfully, to synchronise my iPad 3 with Comic Rack. CR recognises my iPad but when I then expect it to transfer a comic across to the iPad, nothing happens. I have found a 'Synchronise' small black window on the iPad but the 'Synchronise Now' is greyed out. Is that anything to do with anything and, if so, how do I get that to work? Might I have some help with this challenge?
