Convertx AV100U and nerovision express

My convertx AV100U does not work at all with nerovision express 3. Every time it trys to do that scan it does at first, the scan fails on every mode. It also breaks the covertx driver so that I have to reinstall. The video worked with nerovision express 2, but the audio would quit after recording one segment from the vcr. There is no problem with the convertx using powerproducer or ulead dvd moviefactory. Is anyone else having this problem, and did you find a way to get the convertx to work with nve 3?
