I've had the same problem today, only did it on the final update (that adds the radio functionality) though.
It seems it doesn't like using WiFi for this update, so what I did was disabled the wifi on my router therefore causing the joggler to lose connection and make the update fail, rebooted it (unplug and plug in power), changed the network settings to Wired Connection (Settings > Network) and connected the Joggler directly to my router.
This then started the update, so I let it finish and lo and behold, I finally have a working Joggler with the latest firmware. BTW you can re-setup wireless once its finished updating.
I hope i've made some sense and that this actually helps someone, though do bare in mind I won't be held responsible for any damage caused to your Joggler by performing the above stepps (either way, they have an 18-month warranty from date of purchase).
Merry Christmas

I followed the advice given in ashproctor's post and have now managed to clear the problem, which did seem to be due to the internet radio software update. 
For the benefit of other members who have encountered the same probelm, here is what I did:
1) Un-plugged the Joggler and WiFi router.
2) Connected the Joggler to the router with the ethernet patch cable
3) Powered-up the Joggler (which could no longer find the WiFi signal, so did not try to update the software), went into set-up and changed network connection to 'cable'.
4) Plugged the router back in. Joggler connected to the internet via the cable connection and proceeded to download the internat radio update.
5) Once the update had installed and the had Joggler re-started itself, I tested the radio, which was working fine, then disconnected the Joggler power supply and the ethernet cable.
6) Plugged the Joggler back in again, went back into set-up and changed the network connection back to WiFi. The unit re-started itself again and re-connected via WiFi.
7) The internat radio still works fine and I have also set-up the Calander, although I have not tested the alerts function yet.
All credit to ashproctor for comming up with the fix - thanks! Thanks also to other members who replied to my original post.

No problem, I'm glad my "workaround" worked for others
I have to say, I think the internet radio is quite a nice feature, just need to buy an audio cable to hook it into my sound system lol.
