My suspicion was correct.
Although the V 2 player is a non play google version, and the website does NOT say that Google services are required! - MUST run google service!
Website:
Poweramp v2 Poweramp Full Version can be used on device with either Google Account, Email Account (Google Pop3/IMAP), or Yahoo Account registered on it.
The V 2 is running - for. on BlackBerry 10 ONLY with Google Service!
After i installed the complete Playstore (cobalt - forum crackberry), i could activate in a second!
So I was forced to install Playstore - including all available files.
Which ones I might not have needed - I don't know.
So I installed everything from "Cobalt" forum Crackberry".
Btw: ONLY the V 2 runs on BlackBerry 10!
The indication, e.g. using a yahoo mail account is also NOT applicable!
I bought more licenses - e.g. also with the mail address: Yahoo!
- doesn't work either!
Apparently no registered mail account was found on the device!
If you have BlackBerry 10 (requires V 2!) - and possibly the same problem with activation (no mail account registered)
There you go: https://cobalt232.github.io/playstore/
His files on MEGA: https://mega.nz/folder/lIUWjSSQ#yoLoiNX3PNG3Sef1Fa_fMA
I hope, that i could have help other owners of BlackBerry 10.
Every BB user, ho still likes Poweramp app :-) bring money to Poweramp - and happyness to BB owners :-)
Kind Regards
