I live in the UK. Earlier I pre-ordered the Back to the Future game which came with the free game 'Puzzle Agent'. I saved the download to my laptop but when I tried to run the programme the following message was displayed:
Installer integrity check has failed. Common causes include incomplete download and damaged media. Contact the installer's author to obtain a new copy.
I would be grateful if you could shed any light on this as I really don't want this to happen when I am able to download Back to the Future!!! . Thank you!!!
