thank you very much for your help。
I think,it is a bug,i download and install gk_appsprotech_quickstart_J!3.zip,All is ok,
When I upgrade joomla form3.3.2 to 3.3.3, The interface is not the same ,please ,look at the Screenshot ,and ,left mouse button click the hyperlink,no any response, it looks like invalid links
