Import workspace from another computer

Hi,

I have imported all workspace from another computer to my computer in the same path and with the same jdk and version of NWDS

When I open a project from NWDS 7.3 I have this error:

The project for the affected partition is not registered at MOIN: PF.LocalDevelopment

and I can't modify the diagramm.

How can I solve this? If I try to build the project,I get other many error:

Marker file or markers could not be found. partition:Resource-Info: PRI='PF.LocalDevelopment

HElp me...

Thanks

.
