Install English XP S2 on a Korean XP ?

Hello,

I have a computer with a Windows XP Service Pack 1 in Korean. As you can guess, this is really annoying and troublesome.

Maybe more than a year ago, I got a CD for the Service Pack 2 in English, straight from Microsoft. I emailed them to ask wheter I could install this English version over my Korean version of XP, but they didn't seem to know and told me they would email later with an answer. After waiting for a few days, I emailed again and they told me to check with another place, and then to make a call somewhere, but I didn't bother. They didn't seem to really know their stuff.

Now, I'd really like to use XP in English, even partially, so would it be okay to install the Service Pack 2 in English over my Korean Service Pack 1?

Also, is Service Pack 2 worth installing?
