Cant get past the launcher

[MoonRunner]

Am I the only one who cant log in today? It is starting to look like I need to reinstall but I really don't want to waste my limited time with wifi reinstalling the game. I get a patchclientDLL::checkdatfiles failed {unable to decrypt or decerialize data downloaded from server}

I'm sorry you're having trouble getting in. From what little I've been able to gather, you're supposed to use the Repair option in the launcher, which of course just re-downloads everything anyway. Shame you can't get to a faster wired connection, maybe copy onto a usb stick, then bring that back to your main computer?

Someone mentioned a workaround of adding
"C:\whatever directory\Dungeons & Dragons Online\DNDLauncher.exe" -disablepatch
to your game shortcut, but I have no idea if that would work.

You could try an alternate launcher? https://ddowiki.com/page/Launcher
