Spore won't launch on steam.

Yesterday, I bought Spore on steam, and then left it to download over night. When I got up in the morning, it failed to launch, showing two error messages, one after the other :"Configuration Script Failed [2000]"
and
"Could not find a needed package.
The data directory is missing or corrupt [1004]"
I went to the steam forums and tried fixing it myself, but nothing worked. I came across this though:
"go to ea.com, install Origin, contact their support online and tell them, its a known common fault and they will give you spore for free, also grab your CD key from steam also, you'll need to give them that.."
So I hope that you'll help me.
