You can login to the Support site and download the 1.2.7 installer from there if Service Centre is being a bitch.
99% of all Service Centre issues are fixed by downloading and reinstalling the latest version of it (even if you have the latest a reinstall fixes the glitch).
Nice one for the reply Karlos, I’ll try download it from the site later tonight, watching TV with the misses at the mo, she’ll kill me if I go back up to the studio again.
