I've just been trying to build a new CD and PE builder wouldn't work, it just froze on copying setuphiv requiring a reboot.

It did this several time's I even deleted all the contents and extracted everything again same results.

After several reboots I decided to see if it was Sophos, so I turned of the SavService, tried PEBuilder this time it worked.

So it appears the New Sophos is somehow causing a major problem with PEBuilder.

As Sophos is only aimed at business user's for the majority of people this won't be a issue.

Sophos V5.02 fixes the above issue, however it now freezes at the following piont:

Closing hive "F:\windowUBCD\ubcd4win25\petmphive"

I've contacted Sophos again so hopefully this issue will get solved.

Sophos have now fixed the problem, I'm now running V5.04 and UBCD4Win builds without any problems
