I had power kernal installed with h-e-n and everything was fine. I then tried to install nitdroid, but soon realised it was more complicated than I thought so uninstalled the auto installer and went to bed. Tried to use hen this morning and said I had wrong kernel version so I tried to uninstall kernel power using the icon and said unable to reinstall nokia kernel. So I s**t my pants. After I calmed down, I did some searching and used kernel power flasher via xterm, rebooted, but still hen said wrong kernel BUT the uninstall kernel worked. So I reinstalled hen and thank f&!k it worked.

Big thanks to you all and just want to say the answer to your problem is on here somewhere.
