Remapping keyboard

[SIRCOOKS]

I have a UK computer which had a uk windows xp home edition installed. Irecently installed xp pro, a US version, and now my @ sign is frigged up. I can use it cause i found out which key it is switched with, but i wanna switch it back. Does anyone know how to reroute a key board, and what would i need.

Go to control panel, choose category view/Date , Time, Language, Regional options.
Then choose Regional and Language Options/Regional Options tab at top left.

Then use the drop-down arrow and I think that will fix it up. If that is not it exactly, you are in the area that will fix it

Thanks
