Form app. Register-Request returns: "fail", "old version"

[andy-soft]

Hello, tried to make a enroll, and the WhatApp API returned

"old version"

Then I saw a post about the "version-problem", and changed the constants in the WhatsConstants.cs file towards "2.13.440"
At both constants: "WhatsAppVer" as well as in "UserAgent"

After this, it gave a new error response:
"bad token"
(which I saw is elaborated with a complex number and a hash operation)

Is there something I could change to avoid/correct this?
Otherwise the app/api is cool and it (a least) connects, but not authenticates yet!
Also I seeked priorly, the WART website was filled with trojan and viruses as well, beware of this!

thanks
