mount: overlapping loop device

I getting these problems when I try to mount this filesystem DOS/MBR #file bag.vhd bag.vhd: DOS/MBR boot sector; partition 1 : ID=0x83, active, start-CHS (0x0,1,1), end-CHS (0x9,254,63), startsector 63, 160587 sectors #sudo mount -t auto -o ro,loop,offset=82252288 bag.vhd /mnt/floppy/ mount: /mnt/floppy/: overlapping loop device exists for /home/ffha/Documents/descon/bag.vhd. I have been created /mnt/floppy.
