[求助]MATLAB添加工具箱时出错，请高手指点迷津！万分感激！

[cqseu]

按照下列步骤添加工具箱：
1、把新的工具箱解压到MATLAB中的toolbox目录。
2 、在matlab的file下面的set path把它加上。
3 、把路径加进去后在file→Preferences→General的Toolbox Path Caching里点击update Toolbox Path Cache更新一下。

结果命令窗口中出现下列提示：
??? XML-file failed validation against schema located in:
E:\MATLAB\R2008a\sys\namespace\info\v1\info.xsd
XML-file name: e:\matlab\r2008a\toolbox\robot\info.xml
To retest the XML-file against the schema, call the following java method:
com.mathworks.xml.XMLValidator.validate(...
'e:\matlab\r2008a\toolbox\robot\info.xml',...
'E:\MATLAB\R2008a\sys\namespace\info\v1\info.xsd', true)
Errors:
org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'area'.
One of '{MathWorksID, type}' is expected.
