Issues with Mr DNA's FastQ Processor

Hello,

I am having trouble using the app Mr DNA has to remove forward and reverse primer sequences from my raw, demultiplexed data. I follow the instructions (presumably quite well) that Mr DNA provides, yet for some reason when I attempt to combine all of my R1 and R2 files together and remove the primer sequences, it only generates a single empty “demux” folder and a sample-metadata.tsv files. Has anyone encountered this problem before?
