While Opening IBM Information Server[datastage 8.0] client by the previously functioning user name/password i suddenly got an error "Failed to connect DataStage Server ... project: ..... ( The directory you are connecting to either is not a UV or does not exist(39125)" for a particular project.Can any one help me to suggest what may be the possible causes for the error and how to recover the whole project.

Make sure that all services are running, make sure that the UV.ACCOUNT file is intact, and make sure that the UV_SCHEMA table also refers to the project in question. Can you connect to other projects on this server? Can you connect to the DataStage server via telnet? Can you connect from other client machines?
