Got an error when re-training SVM.

I have already trained and saved a SVM classifier file called svm.yml. But when I tried to add one more category to that, this error came out: Bad argument (There is only a single class) in cvPreprocessCategoricalResponse

Does the svm train support a "re-training" in which I append or add additional training vectors and labels to it? I really need to know that. Any help is appreciated. Thanks.

"Does the svm train support a "re-training ?" - no, it clears all internal data, when you call train()

Do you know why this error appears? I have same problem. And i don't think it is related to re-training.
