Data recording problems

I've got a D180 updated with latest firmware. Has been fine in all other aspects but the data files seem to be consistently corrupted. This is first time I've used the data retrieval files for ten years or so so I admit I have probably done something wrong.

When downloading saved data using the standard support program interface to my laptop.
It looks like it has worked - asks me and then tells me it can save as two files - one full data and the other the max-min data. I get it to download both.
But when I open and look at the downloaded files they are unusable.

The full data file has a couple of labels in top left corner but is otherwise completely empty.

The max-min file has what appears to be complete labels across top, columns of data.
But the data is meaningless.
The date and time appears to be correct.
Most of the cells contain just zeros. Which reading around seems to mean that it's reflecting binary state rather than wrong data. So maybe that's correct data.
The ones I am really interested in - CHT and EGT temps. - each column has a figure that is somewhere about a reasonable figure ( I don't know if it's accurate) but it's the same down the entire column. Each CHT and EGT are different from its neighbours but each column is a single number repeated all the way down the column.

So have I just not initialised something? Or is the file corrupted in the Dynon?
The instruction manual seems to be pretty sparse on using the data downloader.

It sounds like those files may be corrupt. Try resetting the data logs in the menu if you have't already, and perhaps changing the recording rate interval setting. But if that doesn't help things there may be a hardware issue going on with the on-board memory recording feature.

I tried resetting the data logs. It deleted the previous files.
But the new files carried the same error pattern.
I've read somewhere in the manual that I can change the data recording rate but now can't find it again. I recall it was somewhere a bit tangential. I found it by chance.

As I recall it didn't say how to do it just that it was possible. So I suspect that was not the "proper" part of the instructions. Can you give me a pointer toward where the instructions to change the settings are?
