    Default NTVDM CPU has encountered illegal instruction

    I'm a real noob, so be easy on me at first.

    I have started easy and was able to program 'Blink' to get my feet wet. It worked!

    I tried some code written for the basic2 stamp after some mods to make it PBP compatable, tried to compile and program and encountered an error msg that I can't shake! I have even tried to redo the Blink programming and arrive at the same error msg.

    The NTVDM CPU has encountered an illegal instruction

    Choose to close to terminate the application

    Close Ignore'

    Anyone have this problem before?

    ps I have been able to go to command line and 'PBP -16f688 blink' and call pbp up using the icon and program the chip,

    Default Yes

    I just started getting this same error message out of the blue today.
    Tried restoring the NTVDM files in windows XP, scanned for viruses (the WWW info suggested that).
    Later discovered I could still compile other code for other PIC types (was using 12F675 initially). I then installed a second new and fresh copy of PBP and pointed MCS to compile from the new copy. No more error messages....

    Looks like PBP or the Assembler was corrupted.
