Earlier this year - had no end of bother saving career after my xbox live gold account expired.
Uninstalled, re-installed, did all sorts of malarky, even resetting the Xbox entirely.
Eventually - subscribing to XBOXLIVE seemed to resolve the problem.
Fast forward to last month, XBox Live membership cancelled, finish career race 2 of 4 last night, Started watkins glen practice, exited the practive back to user menu. turned of Xbox.
tonight, back to race 2 of 4. Anyone else experience this issue. I can't believe you need an XBox live gold account in order for the career mode to reliably save your career.
