Software problem

[Questor44]

Hi, the reason I signed up is my grandsons went together with a so called friend to build a system.  Well the friend seems to have messed up the software?  They are not friends now but we would like to get the system up and working.
 
I have been given the task of trying to figure it out.
 
As the arcade is starting to load we get the message "The front end encountered an error: Script run-time error; handler not found in object."  Is some part of the software missing, or is their some way to do an update to fix the problem?  We have a new Windows Vista computer.
 
I have never had any experience with this so simple is better for me.  I will soon be 65 years young but do enjoy messing with computers.
 
Thanks so much;
Joe Brooks
