Hello,
I have opened a ticket on this, but haven't heard any resolution on this. Internet searches have provided some info on this problem, however, the solution was that Playon came out with a version update...well I have now upgraded twice, and getting this issue. When I try to browse Amazon Videos I get a message box "your amazon user and password are correct, but additional validation is necessary" and when I go to the website, there is no questions to answer. Any additional help would be appreciated.
