I have already took the following actions:
(1) Make sure all permissions are set properly. I have followed the instructions that I could find on this forum. But it does not solve the problem.
(2) I decided then to delete the files and folders related to the following issue: failed to create or download a required files. Again, it didn't solve the problem.
(3) I thought that maybe the origin of the problem was a corrupt files so I followed the instructions to delete the cache. Again, it didn't solve the problem.
Now I don't know what to do and I am totally unable to play. I would like to receive a suggestion or at least know if I should try to delete the game and reinstall it. In this case, will I lost my caracter and my game ?
In order to be clear, I recall what I can see when I try to run the game: (1) A white window appears indicating "checking for updates ..." (2) A second window indicate initializing and then I have to enter my administrator password (even if the permissions are set correctly) (3) I get this message: unexpected error while trying to update, please contact customer service.
I add, finally, that I have Mountain Lion 10.8.4 and that my system is up to date. I own a Imac 3,33 GHz Intel Core 2 duo.
Thanks in advance and sorry for my english.
