@IreneSwift - I ran into this issue about at some point after Origin updated TS3 to 1.69, which was years ago.
I solved that error message by fixing the SKU versions of my expansions. I had few expansions that needed to be updated. SUPERPATCHER doesn't update all the expansions because if you have different country versions, disk versions or Origin versions, some of the expansion SKUs may be wrong. I didn't get an error about the SKU versions, initially. I found that trying to install clean uploads that had items from certain expansions would give me the error that I needed to update my game. That was so vague. I have v 1.67.
But in the laucher, at the very bottom where the EP icons are, I noticed the version numbers of the different expansions did NOT match up to the latest versions for the various expansions. I still wasn't sure what to do and then I had a game crash in which "TS3 Crash Analyzer" reported which EPs didn't match up. Later NRAAS started giving me the report that some SKUs were incorrect. (I don't remember exactly what the report said)
I went to the Wiki and downloaded the latest patches. Here's the link- Please notice the latest patch for each EP depends on region and source.
http://simswiki.info/wiki.php?title=Game_Help:TS3_Patching:Patch_Download/Archived
After doing that and checking that each of the EPs had the latest correct patch, I didn't get the error message any more.
What was wonky was that my game at the time was initially entirely an Origin download, and for whatever reason, the EPs I downloaded had older version numbers although I installed the everything from Origin at the time. But it's all fixed now. I later reverted to disk installs and used the Wiki to ensure my patches were all correct for each EP.
Good luck!
