Can't claim the Steelseries GG Giveaway?

I just get this weird error, been trying since it was announced. Any idea how to fix?

Worked for me yesterday on first try (on Windows), but did you try the standard steps of logging out and back in or uninstalling and reinstalling the app? That might help.
Logging out and back in fixed it for me.
Same issues. Tried all the obvious things, and get the same error.
