So, it still doesn't work, but at least I have a new black box.
Looks like I will be calling the guy from Yuba City to come down after all. But not today. Today I'm sitting on the couch, feeling sorry for myself because of a terrible migraine that has lasted 8 days. I haven't had one of these for a long time, so there's that to be thankful for.
I've tried just about everything I can think of and it seems to only make it worse. Even the nap.
Good thing I don't have any deadlines that have to be met.
