I encountered the 209 launcher error a while ago.
I tried restarting the launcher a couple times in case it was just a fluke. Didn't work.
Clicked the 'Repair' button, and the launcher begins a 30GB download. Wait, what?
Checked my C:\Program Files (x86)\Zenimax Online folder. It's empty, aside from the Launcher and Uninstall.
I rely on satellite internet with atrocious up/down speeds. 30GB will take at least 48-72 hours to reacquire. Not to mention my internet will be mostly unusable during the process.
Get it together, Zenimax. >.>
