this might be a little late, but recently had to reintall/update this program and discovered this issue, and found this thread, i installed a bunch of version (from here https://realterm.i2cchip.com/old_versions__setup/, not sure where to find any other version of this) and found that version 3.0.0.33 was the last version it worked for me on. also there is a gap between 3.0.0.33 and 3.0.1.34 on that site.
