Netprofile and steam crashing?

I see, is there any issue with using netprofile with packaged development build? I was running one client per computer, (one computer hosting a listen server, and one computer connecting), they both have different steam logins, however they are connected to same internet network. client that would crash also started to write a .tmp file that did not convert. If running this command on host listen client, with no other connected clients, it would not crash, but also not convert .tmp file. Perhaps im using this system wrong? I only used netprofile on one computer at a time while trying this out.

Thanks for your assistance!
