My itunes is broken in many ways

My itunes has been really wierd lately

-it cant connect to itunes store

-bonjour wont start

-itunes does not have connection to internet even though i am using it

-itunes refuses to back up my new iphone 5, gets stuck on step 2, makes a bit of progress sometimes but always ends up freezing

I have went to my MobileSync>Backup and deleted all the files inside (ive never backed anyhting up before but there was 1 file on it)

ive updated my itunes, computer, LSA provider (Bigfoot Networks), iOS on iphone and deactivated all my firewalls, no proxys.

i have checked the logs for my mobile sync and it comes up with the long section below. does anyone know how i can fix this? the itunes store not working has been happening for some time already but its the backup that ****** me off. i have to end MobileSync via taskmanager everytime i want to sync new songs to my iphone and it really ****** me off. any help is much appreciated.
