Hi Sammy and welcome the forums!
When you purchased the game from us, you should have received multiple emails. There is one from LDW that has your download and activation information for the game, and one from Plimus that acts as your receipt. The Plimus email will have a download link to the game guide in it. Often LDW email (and Plimus email) winds up in spam/junk mail folders, so be sure and check there.
If that download link has expired, and you cannot download the game guide, (or if you cannot locate the email) you should fill out a
Support Form, and I'll be happy to assist you in reactivating that link and getting your game guide.
Please note: The game guide is only available at no additional charge if the game was purchased directly from LDW for Windows or Mac.
However, the game guide can be purchased separately through
this link.
