This sounds correct.  

Turn on dip switch 5 on the CPU.  This will make the 9 pin port use the default RS232 communication.Default is Host link, 9600, 7, E, 2.  Make sure to set CX-Programmer with these same settings to communicate with the PLC.

Just start a new project set the PLC as a CJ1M-CPU11, choose Sysmac Way as the communication type and 9600, 7, E, 2 as the settings.  Choose the correct communication port number as well.  See if that works.

I will assume that your PC clock is valid, not sure how it would be invalid. I would register your software and update it to the current version (9.73).  If you still have this issue, you may need to uninstall and reinstall CX-One.  I have not seen that error before.

Try to "Clear All Memory Areas" under the PLC pulldown.  It sounds like your PLC may have completely lost its memory and it may be in an odd state.

After clearing all memory areas, try to download your program.
