Ubisoft has had a lot of issues with its controversial and somewhat unnecessary UPlay client. Recently authentication issues have plagued the platform with many users being unable to play Ubisoft's new game Watch_Dogs.
A twitter announcement has been made stating that the issue is almost resolved which is good news for PC gamers desperately trying to play this game. Full credit to Ubisoft for trying to fix the issue but this should never have been an issue in the first place. Hopefully Ubisoft can learn a lesson from this for any future highly anticipated games they decide to make.
