Hey jotek,

I dont understand, why you edited the source (Create New Ticket2), don't do that. Change that back to "Create New Ticket"

You can fix this very easy by yourself - you were already on the right track (/include/i18n/de/LC_MESSAGES/messages.mo.php):

1. Should be line 1739 = 'Open a New Ticket' => 'deine Übersetzung hier',
2. Should be line 154 = 'Please provide as much detail as possible so we can best assist you. To update a previously submitted ticket, please login.' =>'deine andere Übersetzung hier‘,
