Developer Bethesda encourages anyone that downloaded yesterday's problematic release to delete that content and re-download the file, which is free of charge.

The 800 Microsoft Points ($10) expansion brings new quests, items and a post-apocalyptic rendition of Pittsburgh to the action-RPG. A PC version of the add-on was also released yesterday, but was not plagued by floating exclamation marks.

Instructions on deleting and re-downloading the content, follow below. Thanks to Xbox Live programming director Larry "Major Nelson" Hryb for the walkthrough.

• Sign in to Xbox LIVE then press the guide button
• Go to Settings->System Settings->Memory.
• From here, scroll down to Fall Out 3 and press A.
• Select Fallout 3: The Pitt (Marketplace Content) press A then choose Delete, then Yes to Delete.

Now, you can go and re-download the new version for no charge and begin your adventure. Remember, any content you purchased (like The Pitt) can be re-downloaded at no charge.

Also, don't delete anything that says 'Autosave.' That would be bad ;)
