class RandStream has no Constant property or Static method named 'getDefaultStream'

[jagdeeppani]

While running demo of sLDA regression, I am getting

1. The class RandStream has no Constant property or Static method named 'getDefaultStream'

Am I missing something, or is this a bug?
One more point, I had to create a folder "code/io/SimulationResults" to run the code upto this point.

Looking forward for your reply.
