yeah I'm not sure what is going on... yesterday morning it was sweet, it asked me where to put the filer rather then automatically downloading to NMM , It's the unification mod for GOG GOTY that I am trying to get and I am on windows 10 if that helps...

and yeah I've opened chrome>settings>advanced settings, down to downloads and changed where to save the files but itdidn't help and eve when i was in that window it had nothing about files saving to NMM automatically

PLEASE HELP!

NMM uses it's own protocol and downloads to its installation mods repository. You can change it in NMM options.

Chrome has nothing to do with NMM. If you want to download through Chrome you need to download manually.
