So I was recently minding my own business playing some Star Wars: Force Unleashed when in the middle of the stage I was notified I was disconnected from Xbox Live. I proceeded to try and log back in but it told me I could not. I checked the website on what to do and it said to do a gamertag recovery. I did so and was able to reconnect to xbox live. However, I have fewer microsoft points than I did a few minutes ago and I somehow have FIFA 12 achievements, when I have NEVER played or even considered playing FIFA 12. I think someone hacked my account.... I have already taken steps to change my password, but whats to stop this from happening again?
