To Pingu:
In my case the lost key problem ended as follows: a friend of mine suggested me to try dealing with Vienna. After a good amount of emails the following deal was reached: if I had spent roughly the same amount of money in new Vienna licenses as the money I had spent for the licenses I already had on the key, Vienna would have given me back the licenses for the old products as well. Although I wasn't really planning to buy any extra library at the time, however I thought that getting something additional would have been better than just paying back what I had already had purchased.
Well at least that's a happier ending than was initially apparent. I still think the problem needs addressing though, because having to spend a load more money isn't really ideal; nor do I understand the thinking behind it. Either Vienna can restore the licenses or not - why does buying other products help?
I can see that allowing a dongle to be stolen means that there is potentially a new user out there, who hasn't paid Vienna anything - and I can see Vienna saying that we need to do all we can to protect their interests. But at the end of the day thefts happen despite all you can do. And since it is Vienna who insist on putting this rather vulnerable form of license in our hands, if there's more that they can do to make it theft proof, then they should be doing it, rather than simply putting all the burden on us, and then expecting us to share the financial penalty. I don't think people at Vienna are evil or money-grabbing either - in fact they've always been more than fair in the way they've dealt with me - which is why I don't understand the reluctance to at least consider solutions. Let's face it, the dongle is already a big enough pain in the butt - if we're going to have it we should at least get it right. What's the point of something that is already highly inconvenient but doesn't actually get the job done?
