JSE8: UML modeling: xmi.content vanished - model empty

Question

Dear fellow users of Sun Java Studio Enterprise 8,
does anybody know how the following problem can be solved?
We were using the UML modeling features of Studio Enterprise 8 during the last three weeks. We have built a large class model (to large to be viewed in readable size on screen) with approximately 100 - 130 classes.
Yesterday evening the elements (the classes) vanished from the model, while the diagrams were still there.
The only thing we managed to save: We exported the diagram of our largest package as an image.
After restarting the Studio Enterprise 8. The model elements are still missing and the diagrams are as white as a new sheet of paper.
Today I found the reason.
The file projectname.etd has an <xmi.content> tag which should look like:
<XMI.content>
     <UML:Project xmi.id="DCE.4DFCDEFB-3003-25C2-82D8-86B80EEE0FE0" mode="Implementation" defaultLanguage="Java" projVersion="6.1.4.837" name="project_name"/>
          <UML:Element.ownedElement>
               <UML:Class xmi.id="DCE.31A83F15-DD39-5D33-0A64-3F0FC85F1B80" name="element_name" owner="DCE.3C3E618B-9CEE-832E-69DE-6C425C30AD0A">
                    <UML:Element.presentation>
                    </UML:Element.presentation>
                    <UML:Element.ownedElement>
                         <UML:Operation xmi.id="DCE.29EBA057-151F-C131-1C5F-D37B99A0CA80" name="operation_name" isConstructor="true" owner="DCE.31A83F15-DD39-5D33-0A64-3F0FC85F1B80"/>
                    </UML:Element.ownedElement>
               </UML:Class>
          </UML:Element.ownedElement>
          ... more elements ...
     </UML:Project>
</XMI.content>Instead the UML:Project tag is empty. The <xmi.content> tag in our projectname.etd looks now like this:
<XMI.content>
     <UML:Project xmi.id="DCE.4DFCDEFB-3003-25C2-82D8-86B80EEE0FE0" mode="Implementation" defaultLanguage="Java" projVersion="6.1.4.837" name="project_name"/>
</XMI.content>All other files like diagram_name_1148975434695.etld and diagram_name_1148975434695.etlp seem to be intact.
If you know how to restore the content of the projectname.etd file from the .etld and .etlp files, we would appreciate to read your answer here.
Thank you for your time!

Dear Petersl, dear Jyothi and dear fellow users of Sun Java Studio Enterprise 8,
unfortunatly we are not able to generate the diagrams from source code since we didn't generate any source code in the first place.
We were just trying to recall the last steps before the data vanished. This is what we think we did:
We intended to rename the UML project. Since we couldn't do this we created a whole new project grabbed the packages from the model tree in our old project and dragged and dropped them onto the model tree in the new project.
When we were asked to decide wether to import or to move the packages, we decided for import. But we didn't like our packages in the imported elements tree. So we moved them back without being prompted.
Then we moved them to the new model (instead of importing them). Everything worked fine.
Here I have to correct myself: The model elements didn't vanish while the Studio Enterprise was running - they were still there until we finished the program.
We exported the image of our largest diagram, saved (we are absolutly sure we did) and shut the Studio Enterprise down.
When we started Sun Java Studio Enterprise the next day the modell content had gone.
(We are working on MS Windows XP Professional SP2 w/o admin rights. Our usr home direktory is on the network - we get an exception each time we start the Java Studio Enterprise 8 because some logfiles can't be deleted from the user home directory. We also had problems with the installation of Java Studio Enterprise 8: the paths were to long for the network installation software. So we had to install it locally on each workstation by means of temporary administrator privileges.
We use Java Studio Enterprise 8 and we had run an update before the incident.)
I hope this will help you.
Thank you for your time!
PS: What are those Duke Dollars good for? Can you buy something with them?
