Nah dude, it's literally just Windows update, the same thing that should happen in the background on your PC every couple of weeks. Rather than your OS doing it by default in the background, this is a dedicated tool that bypasses what ever problem caused one of the last updates to halt future updates. This in turn will make sure that all of those pesky GdiPlus.dll files are up to date and thus, Easy Anti Cheat won't smell a rat.
It's not a third party updater either, legit Windows Updater tool from Microsoft's own website. It sorted my week-long problem out instantly.
Let me know how you get on,
Adam
