Error code DSU_529

[Libstaaaaaa12]

I'm having real problems with my sky box. I have no apps and whenever I try and upgrade I get the error code DSU_529. 

I have tried the following: 

reset the box and the router 

went into the hidden menu and refreshed apps 

made sure the sky box is up to date and doesn't need updating 

I have literally done everything and I've had enough. Had nothing but trouble with sky I am not happy
