Sending problem SPED-REINF C #

Dear friends,

I'm trying to send an xml for approval to the SEFAZ for SPED-REINF code R-1000, I got help for the methods needed here with the friends of the discussion list. But I have the problem that I do not know how to solve, every file I try to send returns me.

The remote server returned an error: (500) Internal Server Error. Underlying details: Processing failed. Please try again. Identifier: 3033699826

The xml that I'm sending and what follows:
