Hey,

The first error is related to the fact that the RPC Daemon was not started.  
To be able to start the Daemon you have to run the Polyscope software with super user rights. That means you have to write the following command in terminal -\> sudo ./ursim-x.xx.sh.  
NOTE: When you start the Polyscope with su rights the programs directory changes to root. So you will have to create a programs directory in the filesystem root and copy your robot programs over there so you can use them.
