Yes I've updated to 1.24.3.0120xx. I've noticed every time I use an update/patch, I start getting a 'no disc found' error. I already tried using winetricks and selecting Sims3. I don't know if it's done anything because I'm not getting past the first loading screen now due to the no disc error. Might it be best to start again and let winetricks update it instead of updating it first myself?
