@Akerhage and others still facing problems with rooting:
I have finally succeeded in rooting yestarday.
I've tried to follow the rules on this thread but nothing seemed to help me. I tried on Windows Xp 32bit, Windows 7 32&64bit, nothing. I was stuck in the same place as akerhage.
So, what I did was to forget about windows and went linux. I know this might not be to the likes of everybody and that it is just an alternate solution and not a fix to the original problem(s) but it is indeed very easy. You don't even have to install linux ;-)
1: Download the Ubuntu LiveCD with ADB and Unrevoked Recovery installer mentioned here :

2. Follow the instructions there. I chose not to burn it on a CD/CD-RW but put it on a USB stick. Unfortunately, when I tried, the Pendrive Linux did not work for me. So, I recommend using UNetbootin from here :

3. Keep following instructions in the thread by shad0wf0x. There should be no problems.
4. Enjoy your rooted Wildfire.
