What do you expect. Do you really expect ubisoft to release a large update that allows you to play without any issues. This is the usual crap we have learned to love from Ubi.
After months of waiting for this update, the weather is back to that, the game doesn't start on.. come ubisoft this is not good advertising, you can put the BP players to the test..
