It's fine to run DISM and sfc even in the absence of any issues, but they don't fix anywhere close to everything. So if they don't fix your issue, please let me know what happens when you try to play, and also post a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
And make sure your game is NOT set to run as an admin, as described earlier in the thread.
