Linux. First fresh patch to 4.3.0 Live was fine. Then 4.3.0 Hotfix came and ever since I get error 60101 when trying to launch, but the game launches anyway, despite pretending like I need a file verification. Now I downloaded the 4.3.1 hotfix and the patching didn't finish but reported error 5008 and wanted me to try again. Since I don't want to waste bandwidth repeatedly, I decided to take the 4.3.0 P4K from backups again, since that hadn't shown the error 60101. I then patched that to the current hotifx version (which used precious 19 GB of my data plan), and now the damn error 60101 is still there on launch, trolling with yet another thing I have to click to launch the game.
