No worries! If you're having an issue connecting to the maps, a simple reset of your characters' homes may be all you need. Since the new patch replaces the old maps on the server, you're technically attempting to connect to maps that no longer exist. Do be sure you've installed the latest patch from the "Download" page, first!
If you've done that, head over to the main/front page of the Feral Heart website. Select the User Panel in the golden box at the right-hand, top corner of the website, enter in your log in details, and then you will be shown a list of your characters on that account. Select "Reset home" and then "Go home" to each one of your characters. Reload the FH application, and then you should be set to go. c:
