Game disappeared from game list

[BigBossLenny]

Hey guys,

I want to install NFS mw but the game is not in my game list anymore (also not in hidden games).

i know for sure that this is the account where i activated NFS mw.

If i put the CD in my computer and press install, he asks for the serial code and says: code has already been used

(by me of course)

What do i have to do to get my game back?

greets,
