Edrawings issue.

Not sure if I'm in the right area--first time here.  I have a user that is unable to open a drawing with edrawings.  has used the application before.  We have uninstalled 2008, reinstalled edrawings 2009 and when we try to open a drawing we get the message:  EModelViewer Module has encountered a user-defined breakpoint.

A breakpoint in an application indicates a program error.  After this dialog is dismissed, the application will continue running, but it ay be in an unstable state.

Actually, edrawings never opens.  This is a traveling service tech so I have no idea if he made any changes on his pc.

Can anyone possible help me with guidance on what to start to check?

thanks so much
