crash on launch, corrupt journal file

--On Windoze--
I like RNB. I use RNB daily as a journal. Everything was fine till one day I couldn't launch RNB. It would crash on launch. I thought things were normal the day prior but maybe not. Sleuthing brought me to a bad journal file. I would like to know what I did to corrupt it (or if it was me). And a better way to fix it other than what I had to do which was painfully copying text out of the file and pasting back into a new journal for that month.
If I drop this file into a working RNB data folder the program will quit on launch. Remove the file and it runs fine again.
I like RNB but if it's not reliable it's of little use to me. Hopefully it's an easy bug to mash. Hopefully the program could be made a little more robust so as to fix it's own files even if they are a bit out of sorts.
Got a minute to take a look at the corrupt file? Here are the contents pasted into this message:
(thanks for looking!)

4: {text: 'Had a lookyloo at FS1 with Norm Godfrey and Jeff regarding the drainage
    problems around the facility. The conclusion was that we would get a linear footage
    for facility perimeter and call it 10'' wide and 6" deep and see what quantity
    we end up with as a starting point for money.

    ====================

    Todd Winkle, FS3 OTL rejected the DS15-24 P&A L2TRA on grounds that too many things
    were wrong. The L2 would have you believe that this is a highly dangerous operation
    and likely to kill someone. Which of course is not true at all. And other problems
    with it as written too. It was super conservative to the point of not applying
    to this work.\\

    I managed to get Jeff in his office for a second meeting where we went through
    the whole thing to re rank the L2. Turns out it should have been an L1 in the
    first place. \\

    In the interest of doing this work the next day the L2 was changed to be appropriate
    and therefore approved on the spot.'}
5: {text: 'Did the DS15-24 P&A this am. It went very well thanks to everyone pitching
    in to make things better. \\

    We almost had a problem because the DSO thought the L2 said BP safety had to do
    the sniffs when in fact it says IA / BP Safety will sniff. A call to Todd sorted
    this out over the radio.\\

    We almost had another problem because the lifting ring wasn''t named in this operation.
    It totally needed to be mounted before digging so as to be safer. (Less height
    on a ladder.) A call to Todd sorted this out over the radio.\\

    Recognizing:\\

    - Night shift for moving excavator

    - Subsidence for loaning tools and moving barricades.

    - Josh. It looks really deluxe because Josh took the initiative to dress the slopes
    with a shovel while I was digging it. Everybody worked less!

11: {text: 'Dave Smith, electrician, took a look at the Trimble Trailer for follow
    up on the heat (lack of) complaint. He said it is all working at this time. The
    two heaters are 3000 watts. He proposed replacing one of them (that is easy to
    change) to 4000 watts. This requires a different breaker too. He thinks he has
    a heater on hand. \\

    He also observed a gap in the door seal which thwarts any sort of heater.

    I keep taking steps forward but I also keep making tix for new issues because

    Hey BTW, sorry if I forgot to mention this:\\

    Computer doesn''t like GoPro connected to it but if you pull the storage card,
    put it in a micro SD adapter, and put it in the printer''s card reader you can
    DL the footage to the computer. Just be sure to do it read only.

    Cross CPS off the list. Ramp rework was done long ago.\\

    Haven''t heard anything more on the Tarmac pad extension either.

    Would you know where a GDP for S pad 108 P&A would be? It would like to be back
