The first pressing had a manufacturing error which resulted in some CD-ROM drives not playing the disc properly. A notice was distributed, presumably in the next issue of the magazine, stating that replacement discs would be sent out on request.
The replacement disc is shown on this page. It can be identified by the matrix code containing "*DEC97/RE1*", as opposed to the first pressing which simple says "**DEC97**". "RE1" and similar is commonly used by pressing plants to denote parts which have been remade.
The disc contains a Resident Evil demo.
