Unable to Access Framebuffer

I'm a new user of the Mini2440, and set up my environment based on the
lovely post at:
http://equallybad.blogspot.com/2010/02/project-how-to-setup-default-dev-...

However when I run the ./run-hello I get this instead of the output window
shown:

"Using display 0
Cannot create lock file as an old version of QVFb has opened
/tmp/qtembedded-root/QtEmbedded-0. Close other QVFb and try again"

I have no idea what this is! I tried fuser -v /dev/fb0 but that didn't show
anything, and  "fuser -k -KILL /dev/fb0" didn't work either!

Even running as root didn't work!

I've attached the build output as a txt attachment. Please do help me out!
What do I do?

The complete error given is 
""Using display 0
Cannot create lock file as an old version of QVFb has opened
/tmp/qtembedded-root/QtEmbedded-0. Close other QVFb and try again

Can't open framebuffer device /dev/fb0
driver cannot connect"

is it a driver issue?
