Problem Decompiling Maps

So im wanting to decompile bm_crossfire.bsp using bspsource ive tried different methods of decompiling but every time i try open it in hammer it either closes hammer after the progress bar reaches 100% or it hammer opens up and you can see a lil bit of the map in the view screen but stop responding any ideas on what i should do or what other decompiler i should use?

You can try my modified version of BSPSource which has a fix for this issue. See this post.
