I noticed a couple of weeks ago that the link to the ALEOS AF Reference Guide isn’t working. When clicked, it downloads an HTML file to my pc. When it’s opened, it lists links to “Main Page”, “Modules”, “Data Structures”, etc. When one of these links is clicked, the page location is sought in a folder on my pc, where it obviously does not exist.

It’s a good reference, and I’m missing it. If there was a way to download it before, I missed it. Any chance of getting the guide back? Thanks.

Hi @mfp,

Could you please share the HTML file you downloaded from the Source page with me so I can take a look?

Thanks,
