Theme 4.0 and 5.0 can directly open projects from The Observer 5.0, but the project format of The Observer XT has been changed and projects from The Observer XT cannot be opened by these versions of Theme. A conversion program is available which will convert an existing Observer XT project to a Theme project. You will need to register on our site with your Theme license number to get to the download area.
To register, go to http://www.noldus.com/user/register

To download the conversion program: http://www.noldus.com/restricted/theme
You will need the file PatternVision DEP.msi. The instructions are also available as Data Exchange Program Reference Manual.pdf.
