while (my @CFG = <CFGFILE>)
{
   foreach $_(@CFG)
   {
      ...
   }
   print ...
}
[download]

is the same thing as

my @CFG = <CFGFILE>;

foreach $_(@CFG)
{
   ...
}

print ...
[download]

since <FILE> returns the entire file as a list of lines when used in a list context.

Change

while (my @CFG = <CFGFILE>)
{
   foreach $_(@CFG)
   {
      ...
   }
   print ...
}
[download]

to

while (<CFGFILE>)
{
   ...
   print ...
}
[download]

to fix the problem.

Update: You may have other problems; I didn't look deeper. Check out dragonchild's XML suggestion (which I meant to mention myself) and the code he supplied for something better.
