@Simmy86 The problem with this is that it's usually a corruption of sort that can be caused by all kinds of things. So each instance is different. It doesn't matter how it is for others, to solve your issue, only your experience counts.
If the game tells you it fails to load, it usually has an error code on that but you're saying you don't have any ?
Without having further info, it's really hard to pinpoint what's going on.
You say you get an error with MCCC, do you mean like a lastException ?
