When I upgraded from a Brother PE150 to an 8500D, it sat in the box for months, I was afraid to take it out and when I finally did it sat for another couple of months because I was afraid to turn it on - so yes, you are as normal as the next guy!!
I did learn the machine and all it's functions but when I upgraded again to the Innovis the dealer offered classes - I was so relieved!! Have fun, you will love it I'm sure!
