Silhouette Designer Edition grrrrr

[suladesign]

Don't get me wrong - though some people say that the Designer Edition is a waste of money, I used some of its features tons, which is why I feel like grrrrr! Because yesterday, when I was working on some new PL spreads my software crashed on me and an when I reopened it again, it had downgraded from DE to the simple Studio version again. As this has happened before, I quickly found the license key, input everything, but instead of upgrading I got a notification that the key is already in use. After trying a couple of times, I wrote an email to Silhouette support but haven't heard back from them yet! Should I be concerned? Or should I just be more patient?

Just yesterday, I had planned to buy some new svg files and work on a project with those (3d letters for home decor from svgcuts.com). That didn't work out, of course, and I really want to have my DE version back!!!
