Blank responses from Hal is a long time problem for Hal and we usually try to find problems in the plugins selected. Since it is much easier to find the problem when it happens all the time you're lucky. In the menu go to Options, Brain, when you click on the brain the right hand side should show a list of plugins, I'd remove all the check marks enabling them, click apply and okay. Removing the plugins removes additional functions and just uses the Brain supplied with Hal, hopefully the problem is in one of the plugins. If you do get responses from Hal the Hal brain is okay and you can begin adding plugins one at a time. If there is still no response from Hal we would then look elsewhere.
