Yup, i downloaded the winter update on the 22-23rd of December and while i was navigating the new dash it froze, rebooted and got an E68 error. I rebooted and it was fine for a few days then today it's come up again and won't go away. I'd happily get a new harddrive but my 46 hour Skyrim save is on there! i HAVE to recover the save somehow, i enabled cloud saving after i saw the first E68 error but it has synced to a rubbish old save so would still lose about 30 hours. Please, somebody say it'll be ok!
