I have next problem:

Last year in September , I make a project with WinCC Flexible Advances 2004 from PC station. I install WinCC Flexible RT 2004 on PS station.

In December 2005 I bay a license upgrade from WinCC Flexible Advances 2004 ES to WinCC Flexible Advances ES 2005.

Now mast I do a small modification in project with WinCC Flexible RT 2004 on PS .

When open the project in WinCC Flexible Advances 2005, project is automatically convert from WinCC Flexible Advances 2004 to WinCC Flexible Advances 2005.

1. If project is save in WinCC Flexible Advances 2005 she is work properly in WinCC Flexible RT 2004 ?
2. I see “Projec/Save as version “ Is possible to save project from WinCC Flexible RT 2004 ?

In my project “Projec/Save as version “ is inactive, only save is actine.
