Is it just one emb design that does this (not centered), or do all the designs open off center? If that is the case, the machine may need be re-calibrated. Look in your manual for instructions--it is very simple. If it is just the one design that is off center and you do not have the software to allow re-saving to correct position, maybe a friend will do that for you. If I were next door, I would!
I had a strange problem yesterday with a digi'd patch for son. It showed on my 3 programs, did draw stitch 3 times--everything there..count, colors, size, etc. But when I put it on card or on floppy and took to machine, the image was not there. Finally I converted to another format (Hus) and then back to Pes. Solved my problem. Just an FYI in event someone experiences the same. It is miraculous!
