Le sigh.
I figured I’d play some more of this today (I’ve barely scratched the surface-- found the spear of Leonidas for the temple priestess but not much else) and fire up Uplay only to have it tell me that it can’t find the game. So I point it at the installed game, and it says it’s going to verify files, but I click the button and nothing happens. No progress bar or anything.
Windows 10’s Task Manager reports Uplay is using 4.5% of CPU but for all I know that’s just what it consumes in the background anyway.
Well, I had to re-download 20-some gigabytes. Here’s hoping Uplay in its stupidity doesn’t make me start the whole game over again (as it has sometimes with other games).
