I have a PS3 at school and I will be home for winter break where my family also has a PS3. I copied my Skyrim data over to an external HD and I expected to load it up and play it on my PS3 at home, but it gives me some BS about save functions being disabled! I tried signing in with my PSN ID and it says "this belongs to another user". This can't be right. Please tell me I'm missing something. What is even the purpose of disabling all of this functionality??
