Hi karen33333,
The CS errors are 360 errors but the MA error is in V6 box format, that error means the box hasn't completed the update to 360 fully.
You could try turning off the 360 with the switch on the back of the box, then on the 360 box press and hold down both the power button and the + button at the same time.
Then turn on the 360 again whilst keeping hold of those buttons for a further 30 seconds.
The box should reboot, the power button will turn white if the 360 update works, and it should reset and boot up normally.
If that doesn't work you can either call Virgin on 150 from a Virgin phone, mobile or landline, or 0345 454 1111 from any other phone to report a fault, or wait here for one of the forum team to pick this up which might be 2 to 3 day's.
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.
