Before you start to grab the info, make absolutely sure it is printing to the file. Meaning physically open the file up through ftp and see that there is content on line 104 or not.
You'll also need to make changes to the maximum profile line limit variable as it's default is below 50, depending on the version that you have. If you have below 6.6(I believe), you'll want to look for the $mamxmemfield(in ubb_lib_files.cgi) and set it to above 104. In 6.7 it's in ubb_lib.cgi, search for $vars_config{'MaxMemFields'}, changing the value respectively.
