Sims 2 seasons says to insert the disk but the disk is in the drive?

I'm trying to play the sims 2 seasons and I can't because it says to insert the disk. The disk is in my drive! It's clean, has no scratches so there shouldn't BE a problem.

Probably the Disk you are Inserting is not Burned with the game or Burned with An Artificial Installer
Have you used the idea of Cracking the Game this doesn't even needs the Damn Disk
Here is a link from where you may download.

How to Setup
Just Extract the Download to the file where you installed the sims 2 Seasons and if it asks something about Replacing for something Select the Paste and replace Option and you may start the game And by good hopes it will work

This is a common glitch on the sims 2 and 3 games. This has always worked for me:

Uninstall seasons and reinstall

If that does not work you can download origin click add new game and type in the code found at the back of the manual. You will never need the disk
