SUM Still Wont Update!! Shh/Updater-B False positives

After my whole network getting False Positives, and reading pages of post

My SUM still wont update after doing the following

Option 1

1. Add the following exclusions to the' Anti-Virus and HIPS' policy
   
   C:\Documents and Settings\All Users\Application Data\Sophos\
   C:\Program Files\Sophos\
   C:\Program Files (x86)\Sophos\
   C:\programdata\sophos\
   
   
2. Select Groups in SEC and select 'Update Now'
3. Once all groups have been updated remove the exclusions

Option 2

1. Centrally disable On-Access scanning via policy in SEC
2. Select Groups in SEC and select 'Update Now'
3. Once a group has updated re-enable On-Access scanning via policy in SEC

its getting very annoying, all my users are getting a very annoying windows installer window popping up every half hour or so, which causes grief to our dedicated application users, all the log files are full with MsiInstaller Warnings & Errors about

Product: Sophos AutoUpdate -- Internal Error 2324. 6, C:\Program Files\Sophos\AutoUpdate\ps.crl

HELP!!!!
