Sounds to me like your box is faulty, not all V6 boxes have taken to the 360 update. You could try a factory reset.
If you have lost all your recordings and series links you will have nothing to lose by selecting option 2.
You are given 2 options, you could try option 1 first and see if they come back someone said they did but I would be surprised.
If it does it again then you will need to call 150 from your Virgin phone, mobile or landline, or 0345 454 1111 from any other phone to report a fault.
When phoning choose the option to report a fault, then ignore all the options offered and you should then be placed into a queue to speak to someone.
When setting recordings select the Advanced options, one of the options is New Only.
