@Sakura, out of curiosity and interest I watched the first episode of CCS on CR this afternoon and found that it's the original Japanese version. The main giveaways are the correct opening song "Catch you, catch me", all the episode titles starting with "Sakura and....." and the original Japanese character names, Sakura Kinomoto, Tomoyo Daidouji, Toya Kinomoto etc. So the version you saw when you were young was most likely to have been the Nelvana US TV dub where they changed the episode running order and titles to remove Sakura's name and changed her name to Sakura Avalon, while Tomoyo became Madison Taylor.
