Changing CD key.

Ive been trying to change my cd key like i have for the past 2+ months using regedit and modifying the key; but now EVERY key i use it says ' Bad Serial Number Given In Setup ' Soo i looked all around the fourm and i found the Darky Key Changer soo i figured i would use that to change my key. upon start up of the ' Darky Key Changer ' it tells me Failed to read hex key from registry. just need some help getting back on game. Any edvice helps!!

Thanks alot,

Message me on skype: ryanmilton1

Be sure its not set to read only(The key in regedit)then Darky's key changer can't reach it.

Use Darky's

If youre getting (Bad serial key at setup) then you need a new key my good sir.
Edit: Re-read, are the keys youre putting in for change working keys?

i know how to fix skype me cdsisthe1 i just had this problem

I am getting the same error while opening Darky key changer
