Can't workout why my mask isn't working.

you need to set them all in the one form, ie -1 ?l?u?d ?1?1?1?1?1?1
cudaHashcat-plus64.exe --attack-mode 3 --remove --outfile C:\Users\Nicholas\Desktop\file.txt.out --outfile-format 2 -1 ?u?l?d C:\Users\Nicholas\Desktop\file.txt ?1?1?1?1?1?1

in plus it only runs the length you input, so for the command above it will only run for length 6, it does increment automatically in lite
