The code I posted above only fixed problems with FreeEmitter, but it didn't solve the FreeParticleSystem problems (I just implemented switching levels in my game today, and it crashed sometimes even with that code).
The good news is, I just received a private update from Mike for testing, and it seems to be fixed in this. So an update will probably be coming very soon!
