I am a new user. I had installed this interval program a few weeks before this update. Today, I started the program, set the options, made a watering program, and was testing it. My test program seems to be working. I decided to update with the latest version. After the update, nothing worked. Most significant was the loss of the “Options” page, which was mostly blank. I have deleted OSPi directory and reinstalled (several times) with the same results.
