Compressed DTM Taudem Error

Hi,

I’ve downloaded DTM data from the gov.uk open source website, and have then been trying to use MapWindow to fill pits and then process the DTM for flow directions, slope etc. However I get the below Taudem error which says that it is unable to process compressed TIFF files. I’ve extracted the zip folder with the DTM data so it isn’t compressed, and have tried saving in different locations, have allowed MapWindow permission via Firewall settings, and have tried on my personal laptop rather than my work one. This is using version 4.8.8.1.

Any ideas how to resolve this problem please?
