If you lost a lot of things in your computer crash, there are businesses that will recover your lost data from your old computer. I don't know what they charge, but if you lost all your ME designs, it might be worth checking out.
You might also want to start backing up your designs on disks or USB drives. That way, you'll be able to recover them quickly.
One or two of them might possibly repeat, but your surest way to get every one of them is to purchase a membership, which goes on sale very often, by the way. One of the things I really like about my membership is that I can download designs as soon as Miss V. digitizes and puts them up. Also, something I never realized until I purchased a membership is that Miss V. digitizes many, many more designs in a week than the seven or so that she gives away. Purchasing the membership entitles you to download all her former digitizing plus new files digitized during your membership. What a bargain - hundreds for $25 to $30, Hope you are able to restore easily.
