There's a guide in the help file which explains how to use the software and a video on how to make up your own custom rectifiers. Every on-topic question I get on here gets answered by me personally, so nobody is left trying to figure out how things work.
I'm struggling to see why someone would continue to operate a "useless" piece of software between 2006 and 2024 (a total of 18 years!), also you've been a member on here since 2020 and you've been provided with help on every question you've posted.
Congratulations on becoming the first person I've had to block from posting on this forum.
Regards,
Duncan
