Enable Dynamics CRM tracing using Powershell

I needed to turn on tracing for an issue, and thought I would try to use Powershell instead of modifying the registry like I normally do.  I figured that learning this method would work well for some of our multi-server clients.

For some strange reason, I can seem to get it to log anything.  It will create the files, but they remain blank.

Attached is a screen shot of my steps:

When enabled, log files will get created in the Trace folder but remain blank, even after a flurry of activity on CRM.

I disabled, then turned on tracing via Registry, and the logs began to fill up as expected.

Anyone run into this and/or see the obvious mistake I am making?  I even tried on a couple of different deployments.

Cheers
