Well the Sega support have come back to me again this time via phone call and this is the funniest thing yet, they have been asking for the crash dump files but told me today they are unable to read them as there system dont support the format. So all the help they been suggesting so far has just been off the cuff and a best estimated guess at a solution. So needless to say im not impressed one bit, now though they have forwarded my info and files onto Sports interactive to deal but personally it seems like one buck passing off to another.
All i can say is keep poking them and they will have to do something as there are more than they like to admit that are having issues exactly like which we are suffering from, there own forums are plagued with complaints about these issues too.
