the eroor you are getting can be caused by two issues, well I know of two, there may be more.

 

1) loss of session state to popup. If the session variable CESecurity is not pressent then you cannot get there (include_security,asp)

 

This session variable in a propertybag that contains all of the pathing information to the popup

 

2) the second is that you may not have the right permissions set to those directories.

 

What I would suggest is to add temporarly the following line inside include_security.asp

 

response.write Session("CESecurity")

 

shut down your browser, restart it clear the cashe, the try it again and see if you get the same results
