I had the same thing happen for an HR21-700 download. Said it was searching for new software. Showed 021c in top right - my existing version and it looked like it was searching for 0193. It never found it as it went through each item. It then rebooted and I was back to my original state. I don't know if it's worth trying again or not. I'm a bit worried I'll revert to the old 0x16c release that had all of the audio issues. The 021c has been rock solid for me.
I'll probably try again in about 30 minutes.
Second attempt gave the same results. It looks like the new software for the HR21-700 wasn't available tonight.
I had the same issue on both of my HR21-700's. I tried 2 times each, both times they seemed "stuck" searching for software. Both reverted bac to last weeks CE download.
