It has been brought to my attention that there were indeed problems with the offline viewer the past few days. I have received word from the team that supports the offline viewer that these issues were addressed as of this morning.
If you are still having problems, please contact me at
learnmgr@microsoft.com and I will put you in touch with the team that supports this offline player.
Thanks!
