Sorry, there is a intern limitation of .NET. The maximal size of a "object" on a 64-bit-machine/windows is near by 2 GByte. That means in this case, we can have maximal about 532.000.000 height values. 31503 x 25646 = 807.925.938 is too much. You have to split the area in 2 tiles. This all is only valid, if your machine have enough memory. I'm not shure, but i believe on a 32-bit-machine/windows is the object-size only 1 GByte. I have tried other maps and nearly reached 2 GB, so the limit seems to be the same as for 64-bit machines.
By the way, a .NET-program should be run with linux/mono. I cannot test that, but a command-line program should be easy enough. Can you try that? I don't have mono installed on my Linux machine, but wine seems to suffice by now. I tried BuildDEMFile.exe in a win XP virtual machine, but it refuses to work with "BuildDEMFile.exe is not a valid win32 application". Does it have any dependency I should install on the XP machine?
At second, i have used your TRE file with this output:

It is mysterious.
