Ndis Test 6.5 Problems

Whenever I run NDISTest 6.5 manually (not from the HCK), it sits in the preconfig step. There are no errors in WinDbg, and the timer just continually increments. It was working at one point, but now no longer works.

When I run NDISTest (the non .NET version), everything works fine. I need the NDISTest 6.5 suite for the multicast test, and running from the HCK previously took extremely longer (minutes longer) than running from the exe (seconds).
