1. Step back, calm down, pour hot tea, drink, breath in, breath out.
2. Make specs for software, describe what the old script did in detail, do not leave things out.
3. Now you have to choose
   • You start learning Perl and come here to Perlmonks where we monks help you fix stuff and learn to write your own script so next time it breaks you'll know how to put 2 lines together to fix it and not have to rely on some 3rd party
   • You make an ad on jobs.perl.org and pay someone to fix/write it for you
   • Convince her to update the script for you and she's welcome to stop by Perlmonks to ask some questions if she needs help

As biohisham has mentioned I tend to think the last of the 3 options would be most likely to get you some results.
