I have been playing Assassin's Creed III. I downloaded the Infamy (tyranny of King Washington) but it says it works with 1.03. I downloaded the patch but on running it says it updates only from 1.02 to 1.03 and your version is 1.0. Can you please tell me how I may update from 1.00 to 1.03
Sounds like you need to find the patch that goes from 1.00 to 1.02 first, there may even be another step in between. Try and find all the patches and install them in order is basically what you need to do.
