I'm having trouble to open settings tab and when pressing "start play" button it only counts down from 40s to 0s and then stops. Also, when pressing "Find your best deck !" -button I get message: "Login failed: - ERR_RUSH4X_ACCOUNT_INVALID". In addition to this, Launcher.exe can't connect to the server either.
My problem rose at the time of patch 3.8.0.0 . I've been trying to reinstall with little success. All the .dll and .exe are unblocked.
what to do?
EDIT:
I made some research and for an example my WinRAR can't show anything downloadable content when it wants to encourage me to upgrade the free version. Then I found out that the Internet Explorer itself can't access to internet. All other browsers are working just fine. I think this is the source of this problem, anyone have a tip how to proceed?
