Integrating LimeLm into c# .net projectAnswered

I have been trying to integrate your licence system into my c# winforms .net Project.  I created a product and guid from https://wyday.com/limelm/dashboard/  and download the dat file. But I suppose I just need to copy both debug and relase folders turboActivate dll, dat and exe files and add turboActivate.cs file into my Project. 

So I did all of these thing but first there were some issue in ReVerifyNow frmReverify = new ReVerifyNow(ta, DaysBetweenChecks, GracePeriodLength); line. After I attached the form and cs it fixed but I dont think I did right thing. Now ShowTrial(!isGenuine); line has some issue (The name 'ShowTrial' does not exist in the current context). 

I am lost in this article https://wyday.com/limelm/help/using-turboactivate-with-csharp/ and this is not helpful that much for me becuase I cannot understand all of the context. 

Other problem is in  if (!isGenuine && ta.IsActivated()) line because when I debug the code i isGenuine false but a.IsActivated() true but it actually false but it gets true somehow.

readonly TurboActivate ta;
bool isGenuine;
const uint DaysBetweenChecks = 30;
const uint GracePeriodLength = 14;
public loginForm()
{
   InitializeComponent();
   try
   {
       ta = new TurboActivate("xyz");
       IsGenuineResult gr = ta.IsGenuine(DaysBetweenChecks, GracePeriodLength, true);
       isGenuine = gr == IsGenuineResult.Genuine ||
                   gr == IsGenuineResult.GenuineFeaturesChanged ||
                   gr == IsGenuineResult.InternetError;
        
       if (!isGenuine && ta.IsActivated())
       {
           ReVerifyNow frmReverify = new ReVerifyNow(ta, DaysBetweenChecks, GracePeriodLength);
           if (frmReverify.ShowDialog(this) == DialogResult.OK)
           {
               isGenuine = true;
           }
           else if (!frmReverify.noLongerActivated) // the user clicked cancel and the user is still activated
           {
               // Just bail out of your app
               Environment.Exit(1);
               return;
           }
       }
   }
   catch (TurboActivateException ex)
   {
       // failed to check if activated, meaning the customer screwed something up
       // so kill the app immediately
       MessageBox.Show("Failed to check if activated: " + ex.Message);
       Environment.Exit(1);
       return;
   }
  ShowTrial(!isGenuine);
  
}
