Using the app from the Microsoft Store?
If Yes and no respectively, get and use that version.
Otherwise, the answer will be in your latest Windows error log, but you might need a tame techie to interpret it for you.
Navigate to C:\Users\username\AppData\LocalLow
Delete the Cisco folder
Open NowTV Player and it should work.
If this doesn't fix it, delete that cisco folder as well as any NowTV folder inside C:\Users\username\AppData\Roaming
Then reinstall NowTV Player
Tested on Windows 10 x64
Did you also delete the Cisco folder, as described above?
I have the NOWTV player installed on both my PC and Laptop, I can get the service to work on my Laptop but not my PC. On my PC i get the error VGC-4229955698:8.MAIN_CONTENT and when googling this error code I get no results. I have tried uninstalling the software clearing all remaining files and many other things that have been suggested as well.
Can anybody shed any light on this error.
