I tested another code (the 2nd test on the same machine) from the tutorial 
and got error again. I don't know what happened and please help.
Thanks so much.

use Bio::Restriction::EnzymeCollection;
my $all_collection = Bio::Restriction::EnzymeCollection;
my $six_cutter_collection = $all_collection->cutters(6);
for my $enz ($six_cutter_collection){
   print $enz->name,"\t",$enz->site,"\t",$enz->overhang_seq,"\n";
   # prints name, recognition site, overhang
=========================================== Results:

C:\~Scripts>perl t9.pl
Can't use string ("Bio::Restriction::EnzymeCollecti") as a HASH ref while 
t refs" in use at C:/Perl/site/lib/Bio/Restriction/EnzymeCollection.pm line
