\"Attempting to Restore Network Connection\" (Assassin's Creed 2)

Decided to hold a marathon of all the games in the series.
Installed it directly from Uplay, launched, and started giving the error"Attempting to Restore Network Connection. The game will resume once the connection has been re-established. Please wait.
If a connection cannot be re-established, you can continue from the last saved game.
I don't know if I'd played at all in the licensed version of the game, as long as not downloaded, but memory says no.
Get out at each start of the game, with a distinctive sound. The constant flickering of this alert does not close, what to do? How to solve? Found on English-speaking forums something like that, disabled Uplay cloud saving, but it didn't help.
Who met similar how to fix this?
