We ran into this exact same issue when formatting ours earlier this week. The formatting tool does NOT error out when it cannot connect! I discovered that our firewall was blocking it. The program sat and said "formatting" for more than 30 minutes. When the students told me what was going on, I went over, took the Crio out of safe mode, turned off the programming computer's firewall, and imaged the Crio with no problem.

Do you have ALL firewalls turned off on the programming computer?
