DKRed Incorrectly States Hole Sizes are too big

When I upload my files for a 4-layer PCB, I get an error that it cannot use DKRed because the maximum allowable hole size for DKRed is 0.25 inches. However, the maximum hole size in my drill TXT file is 0.125 inches. Here are the contents of the drill file:

Additionally, when trying to upload the 4-layer PCB, DKRed does not bring up the page to choose which files correspond to which layers.

Hello @cvanbeek,

Apologies for the inconveniance, I will direct message you for your files for testing.

I have experienced the same issue. In my case I found that it was being caused by the large opening (6mm) in the copper pour around 3.2mm mounting holes. When I eliminated opening in the copper pour the issue cleared.
