JavaScript Auto Fill code not working in Adobe 8

We do what we call Auto Fills. These are Adobe documents that when brought up from our web site will automatically fill in some data from files stored on the user’s computers.
This is done with the script shown below. These have been working for the past 3 years
With Adobe 5, 6 & 7. Some of our users have started getting Adobe 8 and the script no longer works. There must be some Adobe 8 secret I am missing to change or add to the script to allow the documents to work with Adobe 8.

function StartMe()
{
DataPath = "C:\\seid.dat";
importTextData(DataPath,0);
var Seid = this.getField("seid");
var Seidv = Seid.value;
DataPath = "D:\\users\\"+Seidv+"\\SBU data\\Form9856.dat";
importTextData(DataPath,0);

var DataPath ;

DataPath = "C:\\Documents and Settings\\"+Seidv+"\\SBU\\Stop.dat";
importTextData(DataPath, 0);
DataPath = "C:\\Documents and Settings\\"+Seidv+"\\SBU\\IDRSnumber.dat";
importTextData(DataPath, 0);
var d = new Date();
this.getField("date").value = (d.getMonth()+1).toString()+"/"+d.getDate().toString()+"/"+d.getFullYear();
}
