Thank you SoS & MiniTool.
I was using the free version of this, and now I have the pro one.
The provided key works like a charm, and it’s really the “pro” version.
A few people cry about “not pro version” or “nag screen”, let’s see how this works : every time I’m launching
MTPWP, a box opens up and remember us “there are a few limitations on this version”.
I believe it’s absolutely normal, as it’s a giveaway.
This box has 2 buttons on the bottom : “skip” and “upgrade”. Well, I press “skip” and voilà !
I agree it’s a little annoying and will be happy if there is somewhere an option to stop this.
Anyway, I can live with it.
