I have an ADC-11 USB. Have been using Picolog R5.16.2 successfully for several months. Only complaint was that it would never remember window sizing I set at every use. Today I decided to download an updated rev of Picolog. Installed successfully, but now crashes every time I try to re-open any files -- old or newly created since the update.
I tried re-installing my old R5.16.2. That seemed to go OK, but I'm still stuck with the same inability to open any previously created files. This was not a problem just yesterday before the upgrade attempt.
