Error when tried your method for File Check gyazo.com/56175d226ac0eec9e4a71acc6dc64166
This is a fresh install of the game. I tried a variation of deleting $Patch and or complete files and rebooting. Antivirus / firewall/ windows security/ router firewall all are off.
Tried installing into 2 different drives - SSD with 80gb's of free space HDD with 460gb's of free space. Tried installing on a different pc.
The only thing i did not try is to change the ISP as it was not possible yet.- otherwise its always the same response as shown in the screenshot.
Windows versions used were Win 10 and Win 7.
Thats everything I tried with all the info - hope it helps
