Now we discuss two different problems. 1. The first one is online movement, the Move Joints command.
May I ask you to copy/paste the driver log (you can open it by clicking the "Show Log" button)?
It would also be nice to see a screenshot of the C3 Bridge window at the same point in time.
2. The second problem is about invalid destination path on the robot controller.
You're using default value C:/KukaShared, can you try to set valid/existing paths?
Something like: KRC:\R1\PROGRAM\NEW_NAME.SRC C:\UPLOAD_TEST.SRC
