I have a problem with CC (payment

) in a Samsung Galaxy Tab A, when I want to connect CC in mode "as a wireless device" with my Pc where I have Caliber, always asks me (in the Tablet with CC) enter the pass of: "My Kindle Content" and although I write my pass nothing happens and does not connect, asking again the key. Can someone help me or give me an idea where the problem may be?

This does not happen in the same Tablet with the free version, but, as it is limited to 20 books I thought it would be smart to pay for the full version (was it smart???)

Next time before to pay, I need to visit this forum and read that the project is abandoned by its creators. Now, I need to continue because I have paid.

Thank you very much!
