The game is riddled with glitches it doesn't matter where you play it. If its early in the game, then you being unable to move except a little to the left or right and change the camera angles is normal. That just sounds like when the animus is loading though I can't say for sure because that isn't really a good description. I think you're probably just having a problem with the sound.
Anyway Ani do you know that there is a "Help Me" thread, so you don't have to make a new thread every time you have something to ask. Just saying.....
