Well here I am, I'm the sucker that bought Mastercam V4.0 with out a SIM. But I was able to return it with a full refund. Auction site did not have a clue about SIM. I feel so dum I did not have a clue either. I used Mastercam at a shop I used to work at and I just loved it. I thought it would be nice to have at home. Someday I will. Thanks for all your input good and bad. MDF [email protected]
