MechWarrior 4 mystery.

[mcrue]

I had the same problem but I found the answer in another post. Go download this file:
####://mektek.net-games.com/mech4/patches/mw4nocdv1.zip

Unzip into the c:\temp\exe that you created before. I ran the f2f.exe and hit the crack it button. When it's done it created a file call mw4.exe.bak and I copied it (as well as the mw4 and mw4.icd but I don't think you need to copy those) and pasted into the mechwarrior 4 program. It worked for me. I didn't have to do that unSafeDisc thing with the dplayerx.dll. Hope this helps.
