[Q] Rooting Xperia P

I have just downloaded Root_with_Restore_by_Bin4ry_v18. Running runme.bat gave the following result, which makes me think that things should be o.k.. But - when afterwards trying to install Titanium Backup it says that it cannot do "su". Below is the output or "runme":

If all is successful i will tell you, if not this shell will run forever.

Good, it worked! Now we are rebooting soon, please be patient!

I did notice the "ARE YOU ROOT" line above. I did start "runme.bat" as administrator!!

Any idea what might be wrong?http://forum.xda-developers.com/imag...ies/crying.gif
