just tried it again on my N900 and also on my windows and it works fine for me. can you try uninstalling and then install again ? Im guessing something must have gone wrong while you installed. *EDIT* seems like the registration info goes missing upon re-installing and this clears all user data. Will fix this annoying issue, the currency file should not be getting deleted. anyways for the time being after you re-install, register buddy with the key you already have once again to avoid this from happening again. thanks for pointing out.
