Hi,

from what I have seen, the exception and the missing sources are
actually two different (weird) problems.

Anyway, I assume the problem you encounter is that you get an OS Error
while loading the application, caused by glorp while connecting to the
database. It should not happen, but you can easily fix it by resetting
the data manager. Open a workspace (f6 in the main window) and execute:

MPDataManager resetInstance

This should fix the issue and allow the application to load
(localhost:7777/mailpeek)

For the sources issue, some environment variable got screwed up. On the
main window open the File menu and select 'Set VisualWorks Home'. On the
new window, click on the empty text field and select the directory
/opt/vw771nc

This should solve all the issues.
Feel free to ask if you have further questions.

Tommaso
