Yes, if you want me to debug them. Though I'm not sure if my VC2008 can read PDBs created by your VC2010. If not, only FakeTruth can help you 
It'd be easier to use the exes that I provide, I have the PDBs stored for all of the revisions and VC2008's PDBs can be read by VC2010.
But I think you're running into the same issue as Boo - both your crashes fail in the EnterCriticalSection() system call. I suspect a memory corruption somewhere - some piece of code is forgetting to de-register player objects in time.
