Can't connect to a host server?

I've been trying to run some programs on altair analytics. Most of the functions up top are greyed out, and I can't run the program. Whenever I press Ctrl + R it gives me this error: [ERROR] [Worker-2: Starting connection to host Local] [Line:50] Failed to read Windows registry, exit value: 1. I've attempted connecting to the Altair SLC server, but have not had success. I was wondering if there was some way to go about fixing this?
