When preparing to install LimeWire, I am getting the following error message from InstallShield:

"An error occurred while downloading the file
http://www.installengine.com/isengine/isscript.msi
What would you like to do?"

It gives me the 'retry' or 'cancel' option, and every time I retry, the error persists.
I have Windows XP, cable internet connection...LimeWire installed just fine on an identical computer in my house.
I have browsed the FAQ and the forum...forgive me if I overlooked the answer. Any help would be greatly appreciated...thanks!
