Google Chrome Remote Desktop

I've used CRD to successfully access my home PC (Windows 7) from work (also Windows 7) for about a month, but this week I can't get it to work. My home PC is in the host list, but it is gray'd out and not clickable (see attachment). And even the "last online" time is changing. This morning I disabled CRD on my home PC and then re-enabled it, hoping that might fix the issue, but when I got back to work tonight, it's still not working. I've also tried logging out of my Google account (gmail) and logging back in. Any other suggestions?
