Spore won't load after being installed by steam. You'll find this a lot on forums but nothing by way of a solution, at least not one that worked for me.
Got it working in the end though and here is what I did.
My OS Windows XP
Click play Spore in Steam, game either black screens and crashes with an XP error or simply nothing happens.
Verifying game files which always finds 1 file that needs replaced but seems to replace with another file which also always fails verification.
Also tried deleting various folders etc as suggested by Spore Steam help.
Right click Spore in your Steam Library.
Select Properties from resulting menu.
Click Local Files tab.
Click Browse Local Files
Right click runme.exe
Create short cut to runme.exe and put it on your desktop.
To run Spore and for it to work.
First make sure steam is running and you are signed in.
Second just click the short cut you made and game should load without problems.
