Your old site should be
http://topkayaker.net/cgi-bin/TopYakcgi/ultimatebb.cgi. This is where you replaced the ultimatebb.cgi script with the redirect script?
Your new location in the ultimatebb.cgi script should be
$URL = "http://www.topkayaker.net/forum"
The next setting for me on a windows server with my host I use:
$redirect = 0
Site ID really only comes into play if you have multiple forum installations and should be 1
BTW this posting should really be moved to the proper forum
