Eseries / Communicators :: Nokia E7-00 System Error After Hard Reset

I did a hard reset on my phone today as my phone would freeze at times but it seems that it has given me new problemsFirstly, Everytime I restart the phone, the system error message comes up on the homescreen, I would click ok but it comes up 3 or 4 more timesSecondly, I cannot access my contacts at all, whether I try accessing it from the menu or from a shortcut I have on the homescreen. The software is Symbian Anna, I understand that there is a Belle update but it is not yet available for the phone that is on the network that I am on (which is network Three)I have had this phone since september 2011 and it is under warranty. This is the first time I have encountered a problem.Other than that, everything else works fine; I can install apps and make calls and use the internet etc. I just want to get rid of the system error message, and have access to contacts without having to send the phone off for repair!
