The Bundle in a Box bundles have stopped trading and have posted a message to download all drm free games and make records of your keys before Aug 8th. After that time it will no longer be possible.
You'll need to sign into your personal account to be able to access all of your keys. Once signed in HERE, click on the lost key link at the top right of the page, then fill in the email you used for the account in the field provided. Links to all of your bundles will then be sent to your email. Click on those links to gain access to each of the bundles you purchased. Each bundle does have drm free games, so it will be worth checking and downloading them before the site closes down to ensure you have copies of your games.
