Rainbow Six: Siege - Burnt Horizon (PC) - Freezes on game start after latest update

Rainbow Six: Siege - Burnt Horizon:
I have been playing R6 for a year without ANY problems at all.
I installed the Burnt Horizon update and started the game but now I couldn't play it.
To sove it I de-installed the game (Steam and uPlay), cleaned my Windows registry for any Rainbow Six Siege entries. I then re-installed it, started it, got into the main menu, set display settings to low and started a game... with the same result... it doesn't work!
Got an update today on March 11th. Still doersn't work.
I am in contact with Ubisoft support. They are refering to a (new?) requirement of having a 4 core CPU. It is also strange that the game actually tells me that my setup is okay... and again I have been playing it for a year.
