The NEC drive you have may require a Firmware upgrade. According to the review I just read, it does CD's just fine. However, it is not current as to DVD burning speed. This may be part of your problem. The media you use can have a major impact on what happens during a burn. I have suffered in the past and now use 'quality' Verbatim discs that are meant for the speed of the drives I have (Sony). Please try both CD and DVD discs that are correct for this drive. Ashampoo Burning Studio 6 should recognize the drive without issues.
