Yes this key system is really painfully unfair to costumers. Essentially we are treated as potential copy thieves rather than honest paying costumers. I've contacted VSL several time (I must say that they were always very gentle and responsive despite the poorness of their copy protection system :-) and I thank them for that) and I've asked whether solutions such as
- deactivating the licenses each time you are done using VSL;
- protecting the key with a password
were possible. None of these solutions is possible: There is really nothing you can do to protect your purchase. As I've said before, the whole burden of the copy protection (both price and defects) is on the paying costumers.
I've found a wikipedia page on a similar topic although it refers to the iLok key, however the problems are the same:

I've never payed particular attention to the copy protection systems used in a software I was interested in buying, however, I'll definitely do it from now on avoiding any key/dongle system carefully.
I mainly used VSL SE on my laptop on the train. Essentially I'm not doing it anymore for the fear of loosing my key again, or even just damaging it. Two days ago I got GPO cause there is no dongle and I hope it will serve my porpuses (and I also have one more USB port free :-)). I'll let you know how it went.
I really hope you can solve your key problems without having to spend a lot of money.
Cheers,
