Another thing you could do is see if it's related to the TTLs. A kinda easy way to do that is make a copy of the input file and change all the instances of "ttl:111" to "~ttl:111", "888" to "0,0,1" and "5" to "500". Just to make it a simple text stimulus--does that make sense?
If -that- stops the crashing, my guess would be that it's a TTL issue (genius huh?). If so, we could troubleshoot from there, probably by trying v2012. If it STILL crashes, then we'd go in a very different troubleshooting direction (e.g., scrutinizing the syntax). But as I mentioned before, if these new ones are Windows 7 machines, chances are they simply need v2012.
Hope that helps!
