My phone was reset, now Wordfeud gives constant connections errors. Do I have to reset something for Wordfeud to work?
Try going into
Settings -> Applications -> Manage Applications -> WordFeud and clicking both the
Clear cache and
Clear data buttons.
Clear data may remove your account, so you may have to log back in, but it should help the problem.
If it doesn't, I'd have to say uninstall and re-install.
