Unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib

[manofsteel00]

I am getting the following error message when trying to run a program over the network:

"An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll"

"Additional information: Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed."

First, I am not the author of the code. Second, I have Admin privilges to all network drives and am a Admin on MyComputer. I have googled the error to look for problems, and most said to change settings in the .NET Framework for .NET 1.1. I did; however, I still get the same error.
