Hi, new PC Dell XPS8700 preinstalled with windows 10. Book player does not function. Latest version of Alfa Books and microsoft says I have latest version of net framework. Everything else seems to be functioning. When I right click the play function is not clickable and the audio player viewer is blank. When I double click on file attachment link from book card it opens up Windows 10 default m4b player which is ITunes. I have Alfa internal player enabled and it did not matter if I made Alfa default app for m4b. Afla opened but did not play the file. Thanks.
