Happening for us too. Started yesterday and is continuing today. I checked for updates on my host computer and it indicates that I am up-to-date. Any other suggestions?
It's been 3 weeks and LogMeIn still hasn't come out with an actual fix for this issue! Our help desk has had to spend considerable time uninstalling and falling back to the previous version for most of our 60+ users. Why wouldn't GTMPC just release an actual new update that fixes the problem with an update without having to uninstall and fall back?!
