As the title says. I have uploaded a project to Aisler to test the new plugin, then deleted this project online.
One day later I changed some things in Kicad and wanted to upload it to Aisler and got the Error: "Already logged in" ..
That wasn't very useful, but I figured out that I had to delete "AISLER Project ID: xxxxxxxxxx" in Comment 4 in Kicad Leiterplattendesigner (i guess pcb-designer) -> Datei (File) -> Seite einrichten (Setup Page?) - Sorry I run the german version of Kicad.
After that, I could again upload my project, because I guess it got a new ID from Aisler.
