Xp activator won't accept letters?

[paakwaan]

I have followed the instructions here: http://www.trwhotfilez.kit.net/xpsp1/xpsp1.html

I have a "valid key" but the windows activation says that it accepts numbers only. What am I doing wrong? It will not let me change the key.

My current key is the Devils own XP corp version.

You need not to enter key there but should go to next stage without doing anything and then you can change yr key.

Thank you!
