I have a Nokia C3 and although I am connected to my WLAN, it wont connect to either the OVI store or any internet page. It first says 'A new version of the Ovi store is available. You must download the update before proceeding'. So i try and download it and it comes up with an error saying 'temporary network problem', then straight after that another message comes up saying 'link not available'. How do I sort this problem out???
