EP in NWDS

Hello

When I installed NWDS on my laptop I gave a portal url in the configuration of NWDS i.e windows->preferences->EP. That was one of the clients portal.

Now I want to change the NWDS to log on to different portal I changed it several times, But it is still trying to connect to the old portal. Can anyone please let me know how to change the configuration so that it connects to the other portal or do I have to uninstall NWDS and reinstall it.

Thanks in advance
