Uninstalled the game, and then re-installed it with the disk version. The play button in Uplay changed to an update button. Clicked it. Launcher comes up and does nothing.

I let that sit for a long time and it never did anything.
So i went to the game install folder and ran the gu.exe manually. It downloaded and installed update 1.2 just fine.
Uplay however still shows an update button and wont let me launch it. If i run the sh5.exe manually, that launcher window comes up and does nothing.
Screw ubisoft. Im done. Should have threw this game in the garbage back in 2010 when i first bought it.
