Q1. MEMORY CARD NOT BEING DETECTED
The system doesn't detect a memory card that is inserted, going to settings and system and viewing the screen that shows your memory usage just displays two hyphens.
If a Vita system restore doesn't work, and it won't allow you to format your card then chances are it's a faulty memory card. Send it back and get a replacement card sent out!
Q2. £5 PSN VOUCHER DOESN'T WORK
The pre-order bonus voucher won't redeem correctly or indicates that it applies to a specific game instead of Escape Plan..
Apparently this is being looked into by Sony so I'd keep an eye on their official twitter for now! I'll update this when we know more about the issue.
