Just had the game and first time playing. Was following Altair's son and found it difficult to follow his has Altair locked onto oncoming attackers. Which meant I lost the following and it said it will restart. When I did eventually get passed that it was difficult to follow and escape. The main problem it kept locking but also would not interact with what was happening. I tried to lock onto the attackers but Altair just stood there and if I tried to go another way to resolve it and come back I was restarted! Has anyone else found this problem? I have Win7 64 bit and plenty of memory to deal with the game.
