Hi I'm having exactly the same problems - getting the same error codes and using Wndows 7 and IE 11 - both updated. Never had a problem till prompted to download the new Sky Player, at the start of July 2017 The only difference is I have just downloaded the supposedly 'updated' Player and now I only get a blue spinning wheel !!I I have tried every solution mentioned in this forum - the advice given by Rose-B from the forum team is difficult to understand as it is from 2016 before Sky imposed the new player - previously it worked with Silverlight. Good luck
I re-installed it as suggested. Now I am getting a new error code that I have not seen before: Error code 20000. It asks me to restart the app. When I restart the app i get the same error code over and over.
Had the same problems as you are having... for several weeks. (Windows 7 and IE 11)
I kept uninstalling and reinstalling virtually every day and managed to go through every Error Code that has been mentioned on this forum. Eventually I got the blue spinning wheel. Every time I uninstalled I did a full removal including going in to the 'Roaming' file and manually deleting Sky and Cisco folders.
However, it suddenly started working .. and has kept working. I'm not sure what it was that worked, or why, but here is a list of what I did.
Hard disc clean-up.
Windows update - but specifically any optional updates relating to my NVIDIA graphics card that hadn't been automatically downloaded.
Adobe Flash player update
Re- booted. Then reinstalled the Sky player and it worked.
