Sims 2 won't launch

[pinkwave]

Checked for updates, still not working. I wouldn't be eligible for the ultimate download because I don't have all the add on packs How would I bypass the launcher now? I just have Business, Pets and Seasons installed. That's all I have. I don't really care about the launcher and why would I need Origin now? Never needed it before? Not only does it not work. The Sims 2 isn't even listed. Help me I just want to play. How do I bypass the launcher screen?

Thanks in advance
