Q: What do I do if I'm can't log into Blackboard from my home computer?

You probably have your security settings set too high.

If you use Explorer, you will need to go to Tools>Internet Options>Privacy and put the slider bar to at least medium. Also you can click on the security tab and move the level down on that as well.

You can also click on Edit, key in http://shoreline.blackboard.com and choose Allow.
