Old Roast Time download

Hi! Is there anyway to download old version of Roast Time 3.2.3??
Because the new version doesn’t work in my Surface pro+Win10.
The screen hand-up with no update in roasting mode.

The Bullet reacted to the control.(such as power level change)
But no update to the chart. Nor the temperature or the timer readout.

Any setting error in my computer??

Thanks in advance for any help.

Hi, Just found that above problem on RT3.2.4 happened when it starts after the Bullet starts pre-Heating or while roasting. If I starts the pre-Heating via RT, it works as expected.
