I read in another forum I should update GS to prevent some of the freezing issues. I clicked "Update SDK" (from 18.104.22.168) and it said "Already up to date".
About 10 seconds later, a Gamesparks wizard popped up, which usually happens after a successful SDK update.
I looked back, and it's now .139 -- it did update.
I noticed this happen last time, too. Not a huge deal, but may cause confusion when trying to diagnose what's wrong if experiencing issues and advised to upgrade.
I've updated the SDK multiple times and am not seeing this. It's possible that there is a network issue at play here possibly. I'm not sure what else you could be seeing here.
