refrence apllication extract failed display user inrteface

am doing some testing on the refrence application but now it has failed to display the interface. i have re-extracted it over and over …but it tells me that no user interface module is installed, yet previously the extract was working fine. wat cud be the cause?

Can you clear your browser cache and try again. Or press Ctrl + Shift + R from your browser’s address bar.
