I have in their steam folders *.mdmp files. I opened them in WinDbg and got this output:

I have some problem. Up. – BILL Aug 2 '12 at 21:13
This output ia almost meaningless. After opening WinDbg, can you please do the following: .symfix c:\symbols and then .exr -1 and kb. Then we might come closer to a solution. – Thomas Weller Jan 9 '14 at 12:19
