I've been having trouble posting things to my Wii's Message Board for a month or so, everytime I attempt posting a memo the background goes black and in white text it says the system files are corrupted (no error code), same thing will happen when posting photos on occasion, but I don't post photos that often.

I'm not having any other problems I'm aware of, no problems connecting to the internet or reading game discs or saved data, I can't find anything about this type of thing anywhere else. I don't want to send it in to get it fixed because I'd rather live with a bad message board than lose all my data.

So is there anyway this problem could be fixed some other way without losing all my data, or some setting I'm completely unaware of that got tinkered with sometime in the last 6 months?

I'd appreciate your help!
