[Q] unfortunately the process com.google.process.gapps has stopped

I was updating my Galaxy Note GT N7000 from cm-10.1-20121217-chasmodo-n7000 to cm-10.1-20121218-NIGHTLY-n7000.

I have followed all the steps correctly. Now the reboot is complete and the screen is stuck at "unfortunately the process com.google.process.gapps has stopped" error. If I click okay I get another error "Unfortunately, setup wizard has stopped". Please help. this is urgent. i cant do anything on my phone now.

Regards,
Vishal
