Dear Dietz,
I have never thought that people at Vienna are evil nor I think anyone on this forum does. That's really far from what I think! The main goal of this post was to provide people with the information I was not given at the time I purchased the software and the dongle. Having had this information at the time would have been very useful to me. Additionally, some posts spontaneously happened to provide ideas and suggestions for possible solutions to some of the dongle problems and pointed out how other companies have addressed these problem. I think this cannot hurt.
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.
Cheers,
Cesare
