The toaster will work without the flyer. The software instaler should ask what type of combo it is installing to ie. 4000 with toaster/flyer or 2000 toaster only ect..
When starting the toaster software what screen mode are you in?
BTW 4.1 toaster software can be had pretty cheap on ebay. It is not given away by Newtek as it was a purchased upgrade for all toaster owners of previous versions.
