My problem started with the “We are having trouble transferring data” error while I was trying to update CoD MW. I tried restarting the app, restarting my computer, and changing my region. Nothing worked. I’m now trying to uninstall and reinstall the app, and the installation is stalled at “updating blizzard agent.” It seems like everything fails as soon as I try to reach your servers. My internet connection is fine; I can stream video, play other online games, and download/ update games in Steam.
Hello, I was just having this issue and was tried the things you did but found and kinda acceptable but not permanant solution. Here’s what I did;
I closed battlenet completely (agent.exe and all), Searched CoD MW in google and opened the blizzard link and clicked download and downloaded a modern-warfare-setup.exe and opened it. The exe file opened the launcher itself and started downloading without a problem. (I’m also downloading right now and downloaded around 20gb already)
I hope this one helps you and also blizzard will correct this issue quickly.
