The update for XP&GD v 11 has downloaded and failed.

"Automatic check failed.
The update has been checked and is corrupt. Installation has been cancelled.
Do you want to restart the update process? [Yes] / [No]"

Tried several times now, restarted P&GD to see the same result. Restarted computer, still the same result.

The download doesn't seem to hiccup at all and takes a normal amount of time.
