Thanks for the reply Noel96. Sorry for the delay in answering.

Biab in C:\Bb
Antivirus is Panda A/v 2010
Biab is 2010 build 298
I downloaded the patch and tried to install it, and that is where I ran into problems... it would not recognise my Biab as 2010. At that moment I realised that I had perhaps a more basic problem as I remembered a few little mishaps over the preceeding few days. When re-installing Sonar I was met with a screen saying 'Ms Visual C++2005 redistributable table could not be found' .... so to cut a long story short I decided on a repair install of Win7. All systems are fine now and Biab is working perfectly.
So once again, thank you for your help.
