    Perhaps, restarting the computer will help. If the problem still exists:

    Please make screenshots of your settings for Configuration->Auto Import and Configuration->Database, and send to us by email to support@hand2note.com with a link to your message on the forum.

    @keepcalm Excuse me, but how can i make a screenshot of an application that fails to start?

    Yet, I can provide you some more details on this case.

    I had 2 DBs, one of which i managed to delete (h2n switched to my default DB at this point and restarted smoothly).
    Then, while running h2n at default DB i opened configuration tab, clicked on Create button (which i did several times in the past year) - h2n appearantly shut down, ran DOS-like window telling me it is safely switching (or whatever he tells in this case) and then things got badly wrong: h2n failed to restart by himself nor declined my attempts to start it in this same session or after system reboot.
    Even the text i added in the original post appeared to me only the next day once and never again. My regular routine with h2n now looks like this: i am trying to run it as Admin, the start window appears and then it freezes telling me he is creating a new DB for a minute or two, and then windows informing me that app stopped working and needs to be shut down.

    In search of your advice,
    c1

    Please try to remove the file DbServer.cg that is located in the folder C:\Program Files\Hand2Note by default.
