KC901V Hardware 1.0.4. 1.Problem. 2. Upgrade software?

Hi,
1. I got one of your first KC901V devices. Software version V.1.0.0. Is it safe to upgrade to latest software?

2. My device has problems - noise of plot at high frequencies which makes Smith Chart practically unusable. See attached image. Is there any way it can be fixed?

    Thank you for your reply.
    I switched to medium and low sweep speed – the same problem. Also varied number of points in the plot from 450 to 3150 – same problem. Tried different calibration – User Cal an Sys Cal – same problem. I believe noise/spikes I see is related to heating of the unit. When I turn it on from cold I get few minutes with no spikes. (Unfortunately this time is too short to do any useful work.)
    Below attached plots of the same antenna in the same settings taken at different times: unit just turned on, after 7 min, after 40 min. You can see how initially there is no spikes, than a little bit and in 40 min it is pretty bad.
