having problems setting up cc on my phone

I connected to content sever, and had all my books going to my SD card. But when I tried reading a book, it said I needed a reading program. I already had Moon + Pro, but went ahead and downloaded Moon +. Same error message. So I looked at some FAQs, and used the kindle folder as my download folder. Now I get I cannot connect, because it says the files are read only. Every file has DRM removed, so I have no idea what could be causing the problem except the kindle folder. I get the same error message trying to connect to content server or as wireless device.

I think I am going to copy the settings on my Fire, which is working wonderfully. I will be back.
