Crashing on one family = **corrupt save data** or **bad CC attached to that family**. Fix order:
Neighborhoods\N00X\.Documents\EA Games\The Sims 2 → _Backup. Launch → New hood. Stable? → User data issue.Downloads out. Delete Mods, Thumbnails. Test family.Neighborhoods\N00X\N00X_Neighborhood.package in SimPE.Sims2EP9.exe).CSConfig\Graphics Rules.sgr → VidMemSize = your VRAM.If SimPE fails, family is likely unsalvageable. Recreate in CAS. Backup Neighborhoods regularly.
