In that case I suggest that you repair the phone software using PC Companion: 

http://www.sonymobile.com/update

In PC Companion, press start on Support Zone > Start on Update the phones software > Press the blue link that says "Repair phone". Do this without the phone connected to the PC and then follow the instructions in the program. It will tell you how and when to connect to the PC.
