Please help!

Download your 1.4 projects from the website, or, if they are stored on your computer already, go to the project editor and click “File > Import from your computer” and select your .sb file you want to import.

If you're asking about updating the 2.0 site with 1.4 projects and info, that won't happen until the full release when the 2.0 website is merged with the 1.4 website.

Make sure you have a backup copy saved to your compter for just in case! The Vector Editor(before 2.0 Bimap Editor was released) ate my project Triangle Illusions, but I was recently able to re-upload it.

If your talking about uploading projects here from the 1.4 editor, check out this discussion: http://beta.scratch.mit.edu/discuss/topic/3880/ The ST needs people to test this.
