Launch application AFTER Cisco VPN client is successfully connected

I usually develop ASP.NET pages, so moving to Windows forms has left me with a couple of questions. I'll describe what I'm trying to achieve and then describe what I've already done.

GOAL:
Our remote users connect using the Cisco VPN Client for Windows. I want to automatically launch an EXE that I've written for mapping their drives once they successfully connect. Preferably, this would use Windows credentials that they used to connect to the VPN, but I can live with making them log in twice if necessary.

SO FAR:
I've written an EXE that deletes two mapped drives if they exist and then maps two drives after the user enters a valid username and password. I have also used the Application Launcher part of the Cisco VPN client to successfully execute this program. The problem is that the Application Launcher doesn't wait for the VPN connection to be connected prior to executing the program. Initially I wanted to try to make my program pause for a certain number of seconds prior to execution, but I wasn't able to figure this out and it is really a hack of a solution, so I wanted to turn to the experts to see if you can think of a way to handle this better. Even if my program launched underneath (i.e. my program would be behind the Cisco VPN Client and thus wouldn't be visible until the VPN Client was minimized), that would be fine. I'm just not sure how to force the focus to be on the VPN Client instead of my application.

I'm also totally open to any ideas on how to handle this better.

I've posted the code I'm using below. I've borrowed some from sources on the net, so you may recognize it.
