Slow game download speed in PC + Can't uninstall old version

Hello,

I tried to login into the game (like I successfully did in the morning) and the loading bar went up to around 70% and it failed, over and over again, going really slow in the process. I tried to uninstall the game and I got the well known "Property USER Profile" error.
So, I went to https://www.pokemon.com/us/pokemon-tcg/play-online/ to download the game again, and the download is REALLY slow, like 5,0 kbps (my internet connection usually goes for 5 mbps).
I tried in Chrome, Edge and Firefox, all the same stuff, over and over. Tried a different WiFi, no luck. Tried via a LAN connection, also no luck.
I'm playing on Windows 10 - x64, 8GB RAM, Intel i5-7200U
What's going on?

Please help.

I didn't find the right solution from the Internet.
