( Sorry for my english, i'm french! )
I'm a beginner in this world; and i want to know what i have to do to when my writer sofware say i can't write a CD because he is non-recordable.
It's for the game LNF Manager 2002 and Half life Opposing Force.
I saw on crack sites, i have to download a no-cd software or to rename an executable file.
But i would prefer to burn it.
I have to fix a patch on the CD, install a crack ?
Please help me.
Thanks.
