I am so totally confused. All I have been doing is connecting to Itunes. From there the books I pick out are transferred over to Itunes and then when I connect my iphone or ipad , I would just sync it. Now I cannot connect Calibre to Itunes. I know this is probably a simple fix and I am just having a mind block. Can anyone help me out? Nothing is popping up on my screen -- it just will not connect to Itunes.
