Any joy, Ross?
Nope.
Speaking to my missus on the phone this morning, who usually updates George each day, it turns out that she had downloaded the latest version of George a few weeks ago and had been getting the same error messages appearing but as George still seemed to work, she didn't worry about it.
Next step, go back through the history on the pc to find out when she was on the George website and use the update from the day before for Clearer Planner. At least then I'll only have lost a few weeks history on George. I hope.
I've had a few emails from Rob at Clearer Planner. Seems a nice bloke. He's at a bit of a loss as well and said that the backup file I sent him had yesterdays date. WTF?
