XDS100 v2, Error connecting to the target: (Error -150 @ 0x0)

Hi All,

I am using XDS100v2 from Spectrum Digital with OMAP-L138. I am receiving following error when trying to debug application:

Error connecting to the target:
(Error -150 @ 0x0)
This utility failed to operate the adapter for a custom emulator.
The adapter returned an error for unknown reasons.
(Emulation package 5.0.520.0)

Does somebody know what does this error means?
