Just encrypted my wireless connection...

I just recently got a wireless internet connection and it was working fine. My mom has a laptop too and we were both using the wireless connection. She recently encrypted the connection and now I can't connect. After she encrypted it, she went to Start>Connect To>Wireless Network Connection and a box appeared that let her enter the password. So now she can connect but when I try to do this it just tells me that there is no connection available. It doesn't prompt me to enter a password. So can anyone tell me how I would go about doing this.

 

Need to get into the wireless card's configuration screens and find the WEP or WPA settings depending on which method is being used...
