[PROBLEM] Xbian finds my network but does not ask me for a password ?

[roycejp]

Hi,
I recently changed my SSID name because I changed my ISP and the Wifi router.
Now, XBIAN still displays the old SSID.
When I press ENTER, it scans and finds my new SSID, and displays it thus:
[*****]RJP-DNA, (where RJP-DNA is my new SSID)
When I press Enter, I understand it should ask me my password, but instead the window just closes, and my old SSID continues to be displayed.
I do not have an alternate cabled network, WiFi is my only option.
Please help, Thank You.
