drmdbg works with particular IBX only. And usually after the newer version of drmdbg is realeased, microsoft updates IBX and drmdbg stops working. So freeme2 + drmdbg doesn't work with all IBX versions.

If you can't make FairUse4WM, the only suggestion I have is to install another version of Windows XP, preferably onto a virtual machine.

I'm very cautious about using DRM Reset, because I have no idea how it works.
milOtis has a fix that allows to downgrade IBX and it works for many users.
