Fritzing is closed

Hi, i have a problem, when open the option FIle/Open, the fritzing is closed

First which operating system are you using and which version of Fritzing (hopefull 0.9.3b which is the latest). So you start Frtizing and it stays up? Then you try file->open and Fritzing dies? Do you get the browse file box and asked to pick a file name or it dies when you click file->open?
One thing to try (which may or may not help) is start a debug log. Start Fritzing click help->enable debugging log. That should open a window and may give information when Fritzing crashes. You might also try deleting the user files in case you have corruption which is usually caused by interrupting Fritzing when it appears to hang at first startup. It is in fact not hung but doing (silently) a parts update from github, so after clearing the directories wait for the parts update to complete on first restart (it should eventually ask you if you want to update the parts).

There are two user directories (with your parts and the parts database) which don’t get touched during an install (to not affect your sketchs during upgrades). On Windows they are in

c:\users\username\AppData\Fritzing\roaming\Fritzing (which is a hidden directory so you need to enable hidden directories in explorer) and

c:\Users\username\My Documents\Fritzing (where username is your windows id)

If you don’t have any parts or sketches you want to keep you can just delete those two directories and Fritzing will receate them, or you can move them aside by renaming them if you wan to keep something in them.
