请帮我解决这个问题。

Imports SimpleLPR2

Public Class Form1

    Public lpr As ISimpleLPR

    Public proc As IProcessor

    Public cds As List(Of Candidate)

 

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load  

        lpr = SimpleLPR.Setup()

 

        lpr.set_countryWeight("Vietnam", 1.0F)

        lpr.set_countryWeight("Spain", 0.0F)

        lpr.set_countryWeight("UK-GreatBritain", 0.0F)

        lpr.realizeCountryWeights()

 

        proc = lpr.createProcessor()  ' THis line error. Error show "License expired"



    End Sub

End Class

很显然，我需要一个许可证，但如何解决？
