Lost windows xp sp2 now can't download upgrad

Hello,

After my acer aspire 1501lc caught a virus I lost my internet connection and it basically corrupted the entire computer. I've had to restore the computer to it's original hardware, lost microsoft office (which was pre-installed) and now only have microsoft windows xp home edition sp1 version 2002.

I've tried downloading sp2 but each time it comes up with a message that the computer 'doesn't have the version it thought it had' and thats it.

In addition I've lost my wireless connection, email and at this point my will to live.

I feel like throwing the laptop out the window, but as I'm not a quitter I'm hoping someone out there might be able to help!

Thanks for your time.

Cheryl
