Lost CD-key, and need to reinstall

[icecreamterror]

Lost my little booklet with my BF2 & SF CD-key, and need to reinstall due to some hardware issues.

Are the CD-keys stored in the PCs registry?

Try this:
paFileDB 3.1

or

Run: Regedit
Hkey_local_machine/software/Electronic Arts/
Ea Games/Battlefield 2/ergc

[s]No Electronic Arts/ Ea Games/Battlefield 2/ergc [/s]

ETA: found it, The path for 64bit versions of Windows (Vista x64 and XP x64 editions) is different:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Electronic Arts\EA Games\Battlefield 2\ergc

But the number is alot longer then a CD key 721 characters long!

Seem the processes of patching BF2 results in the CD Key being encrypted, hence my one being so long

But just got another copy off ebay for £1.04

Dose using a second hand one present any trouble, if the key has been used before?
