I find what was the problem, I make a 2 copy of the wallet, in different folder and there create new request address in one of them, but after reinstalling the windows I open the old copy of multibit.wallet that was in another folder, where the new request address was not created, be careful guys))

Before I reinstall windows I have 2 request address in my multibit wallet but after reinstalling when I open the multibit.wallet one of them is gone. And the money what I have on the balance gone to. How this can be possible?
