Re: Critical error
If it's not already the case, download the last QElectroTech version (0.7 rc1) and check again if you got the directory at
to be sure the directory will be created, launch QElectroTech and open an existing project (not create a new one).
Another thing to test, launch QElectroTech open an existing project (make a copy before to avoid a new lost) then open the system monitor of windows and force QElectroTech to close (at the point of view of QElectroTech, it's like a crash).
Then relaunch QElectroTech, a dialog should appear and ask you to open a backup file.
