jhr59, that's because KK does not allow writing to the card.
1. Put iGO folder on internal.
2. Or put on card and root your device
3. Or put on card, don't root your device and add in sys.txt :
[folders]
data="/sdcard/iGO"
In this way only save folder will be on internal .
On this method won't work speedcam and userpoi.
