The box kept freezing when I entered the planner or gave an error message.  Here's how I fixed it.

WARNING - following this advice is totally at your discretion and anything which happens to your digibox as a result is your responsibility, not mine. You will lose all recorded programmes from your Sky+ Planner.

STEP 1 - Soft Reset: Press 'services' on your Sky plus remote, then select option 4. Next press 0, 1, select - you should now see the engineer's menu. Choose option 8, 'Full System Reset'. The box will now take a few minutes to reset itself.
Now try pausing or recording again, and if the problem persists....go to next step.

STEP 2 - Hard Reset: Disconnect the digibox from the mains power. Press and hold the 'left' and 'right' navigation buttons on the front of the digibox whilst you reconnect the mains power. Continue holding the buttons in for about 20 seconds, and when the ring of light on the front comes on, press the 'select' button on the front of the digibox (between the left and right buttons you were holding). The Sky+ recording logo lights will spin backwards and, according to the Sky engineer, this will "clear the hard drive".
Once this is done, disconnect the digibox from the mains power again and this time press and hold the 'back up' button whilst you reconnect the mains power. Continue holding it for about 15 seconds until 3 lights on the front of the box come on and you get a full-screen message saying "Updating system software. Do not disconnect mains supply or satellite dish."
Leave the digibox doing its thing for about 10 minutes and it should be fixed! Try pausing and recording things again.

This second step is what worked for me.
Update1: But this kept reoccurring until I changed my Hard Drive Here is everything you need to know about upgrading the HDD. I replaced my already upgraded 160gb disk with a 250gb 7200 spin speed (as that was all they sell now) and so far so good.
Update2: I found out my problem was not a hard drive issue but SKY software updates which made larger HDD incompatible. See Here
I was able to get around this by disabling automatic sleep mode so my box was always on.
