ArcGIS Desktop 10 Service Pack 1 was NOT supposed to fix the "Invalid Raster Dataset when trying to load ECW" issue (see Eric's post above) but, since installing it, I don't think I have seen this error on either of my laptops, so maybe it was fixed at the last minute.
Is anybody still seeing the error after installing ArcGIS Desktop 10 Service Pack 1?
