Error: [4/9/10 4:12:55 AM] BundleManager GenericActions.FileCouldNotBeFound GenericActions.FileCouldNotBeFound{hw.kb}

I received this message during a workstation upgrade from ZCM 10.2.2 to 10.3.0a and during a new workstation registration after the primary server had been upgraded to 10.3.0a.

Is this an actual problem, or is it cosmetic? If real, what's the fix?

Thanks.
