seems that you just have faced the same problem as me - "the debugger's worker process (msvsmon.exe) unexpectedly exited"
Quick and easy solution for that is just to DELETE all breakpoints:
- DEBUG -> Delete All Breakpoints
and see you son ;)
If you see such message enabling any new features or whatever:
"The function attempted to use a name that is reserved for use by another transaction."
First of all - just turn off your antivirus :)
