After playing Rocksmith 2014 for a week. Today, I can no longer start the game as it appears to be deleted from my uPlay account.
It asks me to input the CD Key and and if I do, it says the says the key is already taken. Whats up with the uPlay servers?

Please sort this out. Many people have the same issue:
