Why wont the game load?

Hi i was tring to load my game called "Spore" were you can create you own games. When i click it this pops up- This Application has failed to start because d3dx9_27.dll was not found. Re-Installing the applization may fix this problem. Then shorty after it says- Spore has stopped working. I've used it all the time and it works fine, but we re-newed are computer so its whole memory was wiped out. I tried re-installing but it still says the same.

Please help me with this problem.
