Could you explain more.

Which apps are you trying to open and what is the error message?

Would suggest trying a restart of your Sky Stream box
Go to Settings>Systems Management>Resets & Updates
Select Restart device
Your Sky Stream puck will perform a reboot. It will take a few minutes to complete

Plus, doing an apps refresh;

1. Press Home on your Sky remote, then select Settings
2. Press System management then Resets and updates and finally Refresh apps.
3. You'll see a message that says, 'Your apps are being refreshed'.
4. Press Dismiss to return to normal viewing. 
   The refresh can take up to 24 hours to complete.

It also may help restarting your broadband router.
