You can use this topic for that:

Here you can find the way to your map of projects.

In short : see at start up of x5 preferences and then you can find the start up map,

usally something like this:

C:\Documenten en settings\jouw computernaam\Mijn documenten\Incomedia\WebSite X5 v10 - Professional\jouw project naam\

have find it but the layout is not.more the same

Then there is no other way then start over again.

You can take from internet the text files and copy these, and maybe also other objects. That will save you some work.

I know it's too late, but, make a copy when finished or aftre making big chances in your project, use step 5 save project, to another medium to stop this from happening again.

Sorry ! Goodluck with the rebuild.
