Need for speed 2 cheats not working

[Waxmaster]

I have tried using a couple of the NFSU2 cheats because I am out of money and cannot find any more races that I will get paid for. The cheats say to enter the cheat on the "ENTER" screen before selecting a profile. I enter it, the game beeps like it accepts the code, however it does not add the cash to my bank. The two codes I am using are well documented and are regmebaby (adds $20,000 to career mode) and regmybank (addes $2,000 in career mode). I'm stuck, desperate, depressed and frustrated. Has anyone ever gotten one of these codes to work? Can anyone help? I'll send you money if you can! Thanks in advance!
