I am getting Viewing Card Not Inserted Error occasionally . It has happened 3 times now. When I switch on the stb it first shows Viewing Card deactivated. Then after couple of seconds the error changes to Viewing Card Not Inserted. Each time I remove VC from box and Reinsert couple of times then it will work for some days.
Any idea why this error is happening? VC is 4 years old but looks to be in perfect condition.
