Hey guys, it's Josh over at Prolific tech support. We are looking at this issue. We always try to look at any issues that come our way, though we always encourage submissions through our website as we don't often visit here.
Regardless, we have some of our people looking into it. We may ask for a bit of help from some people here with Nvidia hardware once we get a better idea of what the problem might be.
Thanks to all you here who are helping each other (and us) out.
