Fyi, if you want to access the sekeletal mesh, a slightly different version of Umodel made by spiritovod now can open it. But in exchange, the LOD now cannot be accessed using this version because it is the main cause of the viewer crashing when open a skeletal-mesh, still a good workaround though compared with NinjaRipper and you can export the skeleton too as usual.

Just use the SDL.dll from another version and it would work just fine.
