Just going to take us about 20 mins to update servers this once, so HideAway might not be available in some locations for a minute or two while we do each server.
You'll need the latest version 4.6.0, so restart HideAway to get the latest version.
Or download here:

[EDIT] We've finished updating now 7:44pm
