Bought the game on GOG, their client won't update the game

[saintshing]

I bought this game on GOG. The GOG Galaxy client/downloader won't update the game by itself(their latest patch was on May 21). Does anyone know if I can do the patching manually? AFAIK, the GOG version is DRM free, so this should be possible.

If the developer sees this, can you pls provide some support to the players over there? Thx!

edit: looks like the developer is aware of this issue and it may be available after the weekend
