Canbus Analyzer 8.00

I have ordered two CANbus analyzers.
One worked, the other I sent back because it did not send or receive, though it got an unique COMPort number. The odd thing is when I received a new replacement, it had the same issue.
So I ended up with one working analyzer, three tried. I can’t believe there are really so many problems with those. I tried them on three different PC’s, it is the same one that always work. What did I possibly overlook?

Another small issue, the one that works can not handel more than 8 bytes of data in a frame. Some PGN’s in J1939 SAE have more than 8 bytes. It can’t be read or written. Can this be updated?
