I was using my phone, battery was low and it suddenly shut down. I thought it's because of battery, and plugged in my charger. Now i'm trying to boot my phone but it's stucking at CYANOGENMOD boot screen:

Here I'm stuck (click for larger image)
Reboot my phone with CWM Recovery mod, and i'm getting no context found error.
I don't know what it's mean and how can i deal with this problem.
I'm using Samsung Galaxy S2 and CWM v6.0.3.3 . I'm not sure how can i find my Cyanogenmod version.
** UPDATE ** I've wait for a long time on boot screen and now "Android is updating" screen appeared. It's optimized my all apps and now and waiting on starting apps message for 8 hours. It stuck at starting apps screen.
