What happened to the v4r5 upgrade - is there going to be a v5?

A few years ago I posted & emailed some bugs in 3dfa (yes, more than one), my project still doens't work because of bugs in 3dfa. Also it works differently in 3dfa internal browser to in internet explorer. I posted a video (AVI capture) of this effect and didn't receive any reply. It looks like there's no upgrades for 3dfa in the near future so, something to consider for people purchasing it now is, there doesn't seem to be much support when there's any bugs found in 3dfa. Even though it says future version upgrades are free, i'm not sure whether there actually are any future versions.
