How to recover MSC cumulative after inadvertent reset?

Make sure Windows is updated. The anniversary update and any cumulative update after that is required.

Are you paying with Credit Card or MSC (Microsoft Currency)?

I understand the issue isn't exactly that it doesn't load, it does, it just takes some time is that correct? It's possible that the connection was interrupted and it had to restart before finally being able to connect.

As I said earlier, it does load eventually but takes longer than usual when downloading a particular event data from the server (I guess). It's all fine as long as it loads. Many a times the loading goes on forever (probably due to network issues) forcing
me to close and restart the app and as a consequence have the entire waiting time along with the time it takes to start MSC again and start/finish the same event, added to the total time. Again, as said earlier, Ads (the BINGO one especially) make it a whole
lot worse.

Whilst most Ads are cached, the Bingo Ad (roughly 60 MB in size--just a guesstimate) is downloaded every time it pops up causing the same issue, only adding substantial waiting time to the cumulative time.

My connection can handle multiplayer games (racing and the like) reasonably well. There's no reason for MSC to be having network reliability issues with my connection other than poor optimization. After all, it's only a one time upload/download of a particular
event data along with the game status itself.

I'll give it a try posting on the link you provided and see how it goes.

I'm having the same problem since the last Windows Update. After running diagnosis it says: Service registration is missing or corrupt. Anyone knows how to fix this? How can I reset the service registration?

ok thank you BUT im still not seeing any MSC or MSP .... I know how much I have but still cannot use this ... please fix this so that my repaired console from XBOX is on the beta
