CMC error in the Opensim2.1.0 b1 gait2392

[Kang Li]

I tried the examplegait2392.
The Scale, IK and RRA tools work well. But the CMC may have some problem. During the CMC,
exception like below showed up. Does anyone know how to solve the problem?

java.lang.RuntimeException: SimTK Exception thrown at AbstractIntegratorRep.cpp:255:
Integrator step failed at time 0.9500000000000002 apparently because:
SimTK Exception thrown at AbstractIntegratorRep.cpp:356:
Error detected by SimTK method AbstractIntegrator::takeOneStep(): Unable to advance time past 0.95.
(Required condition 't1 > t0' was not met.)
