I need some help on App Designer tool

I am trying to make the app designer tool to work but I does only part of it

I installed before step by step installing every thing NodeJS, chrome,
Grunt, android sdk, java and It worked before, it loaded every thing when
run localhost:8000/index.html but last week it did not respond as I wanted
so it runs the app designer and it loads but whenever I want to see ODK
Survey Framework Page on the preview it keeps displaying Please wait and
when I opend the window of cmd it says Waiting as well. If I select on
launch page tab and scroll down to load ODK tables API test page it is ok
as well as Table graphs page. but the other two it does not work.
Previuosly were ok, but now it is not working properly, I can use the othe
tabs in the main menu XLSX converter Legacy XML but Custumized it display
also "please wait" I am enclosing a screenshot. Thanks in advance for your
help.!

You may need to "Purge Database" to clear the table definitions. This is
necessary whenever you add or remove fields from a form definition.
