i got an cd with my brother machine but i can't use it, it says they are in DST format , how can i change them to PES format, pleas help
Where did you get the machine? If you got it from a sewing machine shop, they should not have given you a CD in the wrong format! If you got it from a dealer, you should make them give you the right one.
If that's not possible, and you didn't get PE Design with your machine, there is a program called Embird. It's reasonably priced and you can use it to edit designs as well as convert them from one format to another.
Is anyone out there actually using HusqvarnaViking Embroidery 4D Extra Software on an Apple MacBookPro???
