I installed AOM (trial) here and I think the issue is related to the FVF.
The function initializeFVF is only partially implemented and in case of the 
new code with my patch I see values '0x1c4 / 0x2' while using the old code I
see other values too (0x112, 0x2d2, 0x212, 0x152). So I think we should look
there and check what the old code did. (the code is quite differently)
