I'm sorry you have this experience with FTP Voyager. I will contact you over email and ask you for more details so we have more data to identify the problem. It is the first time I hear about crashing at slashscreen.
actually let's try something different.
I would like to know if it starts up again when you resets application settings and site profiles. All application data for FTP Voyager is stored here:
If you can shutdown FV, rename that folder, then startup and everything works properly, then one of those files is most likely corrupt. You can ZIP them up and send them to me so we can take a look.
