two of us were playing Chap 5 and ended up with 2 id tags (one each) going to rear end of Titan. went to position where you needed two id tags first and used them before going to server room. we couldn't remove the id tags from there (obviously). then went to server room where it asked for an additional id tag. we have been unable to find another id tag to continue...we now believe we did the steps in the incorrect order, and now can't proceed...

Any suggestions for us two chagrinned (sp?) travelers? thanks.
