We had some problems with our update server, that's why we are temporarily changing it to an alternate server, so the "Online Updater" won't work unless you download the installer all over again.
Please, go to our main page at the download section for downloading the game installer again. We are sorry for the incovenience.
This is the download page link: Thereturnofmagic.com
Or download from IndieDB: Indiedb.com
Sincerely, The Return of Magic Online Team
