MiketheWino: Thanks for the replies. However, there is no acvtive links on the game page, at least for this particular game. It's fairly new on GOG, so there aren't even any reviews. Apparently there have been a few players who have rated the game (including me somehow?), but no reviews are showing up. Since I may have rated the game without realizing it (by clicking the star rating), maybe I'm now prevented from leaving a review. Regardless, it would be helpful for there to be some info in the FAQ's. Might be time for me to contact support, eh?
See the attached screen capture which shows the game page in question. Am I missing something?
It looks like you are trying to review the game via the Galaxy client. Try doing so, instead, through the website.
