First of all excuse for my English.
I am the user of your product and until recently with it was very happy and considered the fact of LB's purchase is +EV.
But recently I am very strongly disappointed with that for its high-grade use to me is necessary to have constant hi-speed Internet connection.
You certainly can be understood, you try to be protected from pirates. But, as the majority of other software developers, because of security measures your respectable lawful users who have paid the money for your product first of all suffer.
The theme of online verification of the licence is already in detail considered in the given discussion. I would like to pay in addition your attention to one inconvenience of use of your product - for viewing of video which are a part LeakBuster also is necessary high-speed Internet connection. Recently I had to spend more than 40 minutes to load the video about HUD and all that during that moment at my order was only terribly slow GPRS. Why not to add in your product possibility of local preservation of video?
