The process android.process.acore/com.android.phone has stopped unexpectedly. Please topic

This morning I tried to turn on my motorola xt-532 and right after the boot I get this two errors:

"The process android.process.acore has stopped unexpectedly. Please try again."
"The process com.android.phone has stopped unexpectedly. Please try again."

I can't do anything, because as soon as I press "force close" they appear again and again..

Any idea?
