• Check that you have entered the login/password correctly. These are case sensitive.
• Make sure that your computer is connected to the internet.

If these do not fix the problem, then the problem is caused by a firewall (often found in internet routers) blocking the software's access to the port necessary to connect to the internet (port 3131). If you are using a software firewall then it is simplest to temporarily disable the firewall. If you are using a hardware firewall (or router) then you will need to use port forwarding.

Software Firewalls

Software firewalls can be disabled by either closing the firewall application (McAfee, Symantec, ZoneAlarm etc) or by unblocking port 3131 to the Motorola Unlocking software. If you are using Microsoft Windows XP firewall, Windows will ask whether you would like to give the software access to the internet.

Hardware Firewalls

is a great resource for instructions on how to use port forwarding on a range of different routers. Go here for instructions on how to use your router to forward port 3131. The option to allow UDP on this port should be enabled.
