Hi Folks,
I don't know if this will help anybody but I recently changed over my PC and had a *ton* of CORBA errors during download.
By switching the USB cable (the original one used was one I pulled from a box of cables, so I don't know it's origin) used to download to the TWR system, they basically have all gone away.
I tried different cables, USB ports as well as different PCs, but found that the common point for failures was the single USB cable (which works fine in other applications).
