Glad to hear Cake is on it. Meanwhile, I waited (multitasked, actually) long time through each of the pages and actually got to download the delay unit. Then installed it. Then set up the necessary Overloud account to register the product. Then went back to account page and the formerly blank serial number space finally refreshed with content. But instead of a serial number, the field says "
Out of serial numbers".
Posting here in case repair folks aren't aware of this variation of the problem.
Oh well, guess I'll look again later or tomorrow to see if they put more numbers in the hopper.
