Problem with Cell Designer compatibility with SBML (xml) files

Question

[myasemi15]

Hi, I downloaded a model from this website : http://jjj.biochem.sun.ac.za/models/ the model is related to MAPK Pathway, I was trying to open the downloaded file, which is in xml format in Cell Designer software, but I got the error shown in picture, while I can export my models from Cell Designer to this website easily! Any comment is appreciated... I'd be thankful if anyone who knows about SBML can help me. I'm new to this language...
