hi,

i have installed SDK tools 20, it used to work when i was using 18

but now adays when i try to create a VM i got this error http://d.pr/i/lXup which is related to the sdcard ..

i tried to create a card manually and attach it to the device .. but the device stuck on the android logo and thats it ..

am using titanium so here is the log
