Vdownloader problem

Hello, someone responsible for support. Several days ago I bought the definitive right to use vdownloader, which I regret a lot, because you are failing to answer me or present a solution to the problem of crashing the program after the update was made. definitive purchase. I no longer know that a number of times I contacted you reporting the problem and asking for a solution and until now I am waiting to be attended to. Pegunto, what do I need to do to have this problem solved permanently?
