It involves a bit of messing about but can be done.
Open Blue Voda (new blank page).
Goto File > New Page > from existing HTML page
Set the radio button to Remote (for internet)
Type the URL of your web page.
Your page will appear on your screen BUT you will probably have some work to do with it before you can save it as a .bvp file again. Sometimes i-frames are messed up and sometimes objects are duplicated.
This happened to me several months ago, you have my sympathy. Good luck. And do some back-ups when you get straight!!
