Unfortunately, I didn't get adequate help. I would like to try an older version of the Helikon Remote. With the older version, there was no problem. How can I get older versions?

I sent the error report after the error occurred.

These days, this problem has been bothering me a lot.
I replaced the cable first. Then I tried on another computer. The result was always the same as Elizabeth described. I ended up getting another D7100 camera, which produced the same error.
It is definitely a problem in the helicon remote software ...
