For the benefit of the other users, I was able to get this fixed with the help of the online chat. Basically, if you are experiencing this problem, you will need to clear your cache on your desktop studio player by deleting the signage studio player folder and resigning back in. You can find this folder at this location:
C:\Users\USER_NAME\AppData\Roaming\SignagePlayer.XXX . Do not delete the "signage studio" folder but the "signage studio.xxxxxxxxx" folder
