Whenever DB has an update through the client, it will update but then a message pops up saying that an error occurred during the update process, as shown in the uploaded image.
Demonbuddy will still update successfully, its just that the update crashes afterwards.
silveredu probably should make your own thread if you need support but i can tell you yours is not working because the devs are working on a patch for demonbuddy keep checking back for a updated version to be released
