When I got the patches for Pets they offered two patches, one says Sims2-Pets-Patch-CD and one says Sims2-Pets-Patch-Digital. I didn't know which to get so I downloaded both...the same for Seasons but no other EP's had this. They all said just patch. So my question is which one do I use?
If you are using CDs to install the game, use the CD version. If you have the digital versions (downloaded from the TS2 store), you'd use that. I think you said you have actual discs, so that would be the CD version.
