Nokia :: N97 OVI Facebook Error / Incorrect Signature - Status

I have had my n97 for about 2 weeks now and I have not been able to use the facebook application (from ovi) at all. I am with Optus and can access facebook via the web (Optus Zoo), however I cannot use the actual Nokia facebook application.Whenever I try to access the application it takes me to the log-in screen for facebook, and once I have entered my username and password it thinks for a few seconds and then tells me: "Error occurred. Incorrect signature, status: 104"I have looked through forums on the web and it seems like it is a pretty common problem for the Nokia phone. Everything I have read in various forums has lead me to believe that Nokia don't know how to fix the problem either, or just don't care.I am getting really, really, really frustrated with it. I am pretty addicted to facebook and love playing facebook games.
I am dieing to kill some time during my commute by playing some games, and because I can't use the proper application, it would seem I can't play the games.
Can anyone please tell me if hey had this problem and were able to fix it? Did you have to get in touch with Nokia? Were they any help?The forums seem to show that people have been advised to remove the application and reinstall and to clear their cache/browsing history. However, I haven't come across anyone yet where this has actually helped the problem. I haven't come across a single person yet who can actually use the facebook application either.
