Error running child packages from parent package - Error 0xC0011008

Question

Hey...
I am running a parent SSIS package (running sp2, 9.0.3042) that calls several child packages.
On our development server, we now cannot run this because we get 1 or more of these errors:
"Error 0x80004003 while preparing to load the package. Invalid pointer  .  "
"Error 0xC0011008 while preparing to load the package. Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.  .  "
It is not occuring on the same packages.  It varies every time it is run.
I can run every one of the child packages individually, using the same login ID that the parent is executed under.
The parent package works fine on my local machine and other servers running the same version of SSIS.  Just not on this server.
Does anyone have any ideas???
Thanks
BobP

I have the same error with no parent child package relationship. I have changed the "Max Concurrent Executables" in each package from -1 to 10 and got  no change.  My code is below:
List
<string> fileList = new List<string>();
private
void checkedListBox1_SelectedIndexChanged(object sender, EventArgs e)
//this.fileList.Add(checkedListBox1.SelectedValue.ToString().Trim());
this.fileList.Add("name");
private
void button1_Click(object sender, EventArgs e)
string @fileName;
foreach (string str in fileList)
@fileName = str;
string pkgLocation;
Microsoft.SqlServer.Dts.Runtime.
Application app;
DTSExecResult pkgResults_Sql;
pkgLocation =
@"C:\" + @fileName + ".dtsx";
app =
new Microsoft.SqlServer.Dts.Runtime.Application();
Package pkgIn = new Package();
pkgIn = app.LoadPackage(pkgLocation,
null);
pkgResults_Sql = pkgIn.Execute();
