Dumb question on Google's page preview

Hey guys,

Sorry for this technical question, I know this is not the right place, but I really don't know anywhere else to ask.

I have a flash website, and in Google's page preview it only shows the "Under construction" message I had a couple of weeks back (when it first indexed).

Does Google automatically refresh this? It's been a few days already...

Is there any way I can "force" Google to refresh the page preview?

Thanks in advance for your answers, and again I'm sorry if this is not the right place for this kind of matter.

When google crawls your site again, the page preview will change.

and obviously Google doesn't consider your site very valuable so it might take at least a few days more for Google to update that stuff...
