We are trying to do an enterprise activation with the Blackberry Simulator as mentioned in the following post

 How To - Connect the BlackBerry Simulator to a BlackBerry Enterprise Server

Summary
This article applies to the following:

BlackBerry Enterprise Server™ 4.0 and later
BlackBerry® Java™ Development Environment (JDE)
BlackBerry Simulator 4.0 and later
--------------------------------------------------------------------------
Procedure
Using the BlackBerry JDE 4.0 (or BlackBerry Simulator 4.0), the BlackBerry Simulator can be connected to an account on the BlackBerry Enterprise Server.

Run the BlackBerry Simulator from the JDE or from the Start menu.
In the BlackBerry Simulator, click Turn Wireless Off.
Open BlackBerry Desktop Manager 4.0 or later.
Open BlackBerry Device Manager 4.0 or later.
From the BlackBerry Simulator, click Simulate and select USB Connected or Serial Connected.
Select YES to switch to the new BlackBerry wireless device.
Follow the instructions to generate a new encryption key.
On the Initial Plug-in: Verifying Applications dialog box, click Cancel.
Once the initial synchronization is complete, the enterprise activation begins.
After the enterprise activation is complete, you will be able to use the BlackBerry Simulator like a regular BlackBerry device.

Note: Additionally, you may need to remove the net_rim_sdk_simulationSB.cod file from the BlackBerry Simulator directory. However, do not delete this COD file because you will need to restore it if you use the BlackBerry Simulator with the Email Server Simulator (ESS). After doing so, delete the DMP files from the BlackBerry Simulator directory, start the BlackBerry Simulator, and repeat the steps above.

To verify that the BlackBerry Simulator has connected to the BlackBerry Enterprise Server using Serial Bypass, complete the following steps:

In BlackBerry Device Manager, click the Statistics tab.
If the BlackBerry Simulator is connected, you should see Bypass. Expand this menu to view statistics (for example, packets sent/received).
OR

If only the Time Connected statistic appears, without the Bypass statistics, the BlackBerry Simulator is not connected to the BlackBerry Enterprise Server over Serial Bypass and the enterprise activation cannot occur. Delete the DMP files from the BlackBerry Simulator directory and complete the above steps in order to remove the net_rim_sdk_simulationSB.cod file from the BlackBerry Simulator directory. Alternatively, you can attempt this procedure with a BlackBerry device to verify that your BlackBerry Enterprise Server configuration supports Serial Bypass.

But after connecting the Simulator by clicking on USB Connected option in the Simulator, we are not getting the "Select YES to switch to the new Blackberry device" option anywhere. Can anyone suggest what might have gone wrong?
