Or, so Windows 7 says. 
I have Logos 4 Windows installed on two computers, my desktop and my laptop. Today, each of them downloaded an update, and each of them has stopped working. No error message, nothing I can see. I start the program, it comes up and shows me the screen and then freezes. On both computers.
I uninstalled it and am reinstalling it (4.46GB download...yay?) on my desktop and I will report back if this fixes the problem, but if anyone knows what's going on with this most recent update that might have caused this to start happening, that would be really wonderful.
Thanks in advance for any shared knowledge!
