Unable to Start Game but Pets DL worked perfectly

I followed the download instructions exactly as they were written and was playing the game last night. This morning, I turned on my computer and now receive the error message:

'Unable to start game.

Your The Sims 3 Base Game is incompatible with the current Sims 3 Expansion Pack. Please updaye your game via the game launcher.'

When I try to open the game via 'Sims3LauncherW', the launcher opens with 'Version 0.0.0.0' at the bottom left, and an error message saying:

'There was an error during startup. Please see the log for more details.'

How can I fix this without uninstalling and reinstalling my whole game?

Thank you!!

Hello,

Have you try to update the game Manually to the latest version?
