Error code 12

[Neena]

Hi there

Last night i was playing WA and when my sim returned home from egypt she and her family were all frozen.
All there needs started to slide into the red. Then I recieved a message saying that there was an error code 12 and to
check the read me file. I did this but this didn't help. What is this message and will it happen again. I have emailed
customer support.

Thanks.
