Ok, well. I found the answer to commands (keystrokes) not executing.
This issue is "Missing Key Binding." The missing keystrokes need to be bound to ANY keyboard keys to work. You can find the list if you open configuration settings for the HCS voicepack you bought by saying "Protocol Override Configure my Settings." Then clicking the "Missing Key Binds" button on the middle right of the pop-up. For some reason the [Left Ctrl, Left Alt, Left Shift + Enter] doesn't open it now as it should.
I couldn't find this information online. I hope this might help someone else.
