Problem getting part to mesh

Hi,

I've been trying to run a quick simulation, but have not have been able to get this part to mesh. I can say that it has something to do with the center links of the frame because when I remove them, then the meshing works fine. But I can't find the source.of the problem. (I also have no access to any failure diagnostics)

Part is attached.

Thanks.
