Hi Nathaniel,
We are aware of this problem and we are trying to figure out root causes and solve them as we find them. The eye tracker getting stuck in initializing can be caused by a number or underlying issues, so even though we have hunted down and solved some, there are still some even harder to track down issues we haven’t found the root cause for yet. But we are working on it…
The only suggestion I can give you at this point is to try and restart the computer and see if it helps.
