MEGAN6 loading up with a blank screen/no screen

I’ve been using MEGAN6 without problems on my Windows 10 laptop for a while now. On the 14th I went open it and load up a Blast file. What I got was two windows I can’t click on that are blank when I hover over them:

This is what I get. Sometimes but not always I get an error Failed to open files: ncbi.tre and null. I can’t find online where I would find working copies of these and where to put them within the architecture… Because it can’t load up, I can’t go into Preferences to edit them and find where they go.

Any help would be appreciated!
