Hello everyone,

Several dasy ago, I had installed the DS 2.1 in the windows system of  my PC, which had been connected to pipleline pilot successfully and i had performed the protein modelling with the protocol present in the DS. But today when i open the DS 2.1, there is no protocol seen. In the bottom of the surface, the server displays the previous address i used, which is not "server:none". Dose anyone know what's wrong with the DS and how can i to solve this problem?

Thank you.
