Importing a particular quality material from Fab not working

Hey there everyone,

when I import a material from Fab (Quizel Megascan particularly) it doesn’t import all the Material Quality types (e.g. it imports low and High but not Medium, or medium and high but not low). It starts and ends to import but material doesn’t show inside the content browser, even if I restard the software. Or sometimes the download window opens but then automatically close withound downloading and stopping at 0%. Does anyone know why? Thnx in advance mates, hoping to not be out of topic.
