I don't have a gypsy or a cricut (gave mine to dd and sold my E) but I read this on another board. Not sure how true it is but knowing PC I believe it could be.
Gypsy users are now being told that if you update, and your Gypsy is no longer under warranty, do it at your own risk. They (Provo Craft) will not be held responsible even though it is their released update. They are aware that failures in the download are occuring that kill the Gypsy.
