I am not an expert on Nuuo but it sounds like more of a PC problem then the card itself. I would recommend calling James again and have him walk you through updating the Drivers again, because when you reinstalled the software you may have overwritten the new drivers back to the old ones, causing you to have the error message again. This may fix your problem with the errors, but also not sure how you installed it but Nuuo cards require you to install the software and drivers before you install the card or you will usually have these problems.
