Error installing the 1.22a patch on warcraft 3 frozen throne

Hello everyone, i am new to this forum and i have a little problem here. I use to have the 1.21b patch installed but i want to upgrade to the 1.22a patch but i always get this error message: ERROR: unable to load file 'Abilities\Spells\NightElf\shadowstrike\shadowstrike.mdx' from archive (War3Patch.mpq, war3.mpq)
I don't know what might be causing this, but i need a solution quickly!
Thanks a lot guys!

Sounds like a corrupted download to me. Try downloading the patch from another source.

Well, i downloaded it from the blizzard support page. How can it be corrupted. And by the way, the game was given to me by my friend. We all use the same serial number that is why i cannot play online.

Well now, if you had read the forum rules, you'd know that aiding and abetting piracy is very firmly against the rules. SHAME SHAME SHAME!
