Right Sidebar Widgets Disappeared

I’m new to the technical stuff, but am familiar with the dashboard functions from wordpress.com. I switched today to a .com domain so I could monetize my blog. However, while trying to set up my affiliate ad codes, my right sidebar widgets disappeared. I’m sure it’s easy to fix, and that I’m just missing something, but I’m not sure where to start to resolve the issue. I’m using the Arras Theme, by the way. Any help would be greatly appreciated.
