Hey there, I have a little problem with aol, msn, aim and yahoo. While i'm logged on aol, i cannot log on aim, msn... So i ran CCleaner 1.40 and now i can log on msn but NOT on aim or yahoo... I see that CCleaner do not clean those files and i was wondering if i could add aim and yahoo to be cleaned ? Sorry for my bad english and thanks for the answer !
