Language setting problem with spellcheck
 

In Microsoft Excel I was making a multi language sheet, and I was tired of
the english spell check wanting to change my spanish words. So I ran
spellcheck and saw a spanish language pack setting. As the option was listed,
I thought that I had a language pack installed. As it turned out, I did not.
I bought this Windows XP computer with the programs pre installed.

When I tried to start up the spanish spellcheck, it would not run, saying
the feature was not installed, and asked me for the disk containing the
language pack. I cannot find any such disk.

I am unable to change the setings via starting the spellcheck. I do not
really want to uninstall excell. I tried system restore, but that had no
effect. Is there another way to restore defaults for excell?

I am a home user who does not use it for complex things.
