CLOUD SAVE CORRUPTED?

Hello everybody and sorry for my english, i m french! (trad online…)
I have a big problem, I bought the one X and i can not recover my save in the cloud.
the error message in something like that: Cloud synchronization on the other Xbox takes a lot of time
I have contacted xbox.com and make a reset keeping the games…
But it did not work.
my GT is cpc02
Many thanks

So… did you let it fully synchronize?

yes but it does not download the save, I have an error message It stops at 0%
I have the problem just with forza7, it’s their server!
