FTP Login Prompt on Tab Group with password stored

Yesterday I created a few Tab Groups for opening a local source folder with an ftp destination. Today every time I open any of the Tab Groups an FTP login prompt pops up. In the ftp address book I have it set to store password and it works fine if I click the location in the folder tree but if I try to open the Tab Group it keeps prompting for a login. So how do I get the Tab Group to remember the login details again?

Ok so I've figured out that if I first click on the FTP location in the folder tree it connects automatically and then opening the tab group also connects automatically. I guess this means the login details are directly associated with the ftp address book entry but not the ftp path stored in the tab group. I wonder if I increase the Cache site passwords to longer (maybe two days) would it rember it for the next day.

Ok so I found this post which says to use @sitename from the address book instead of an ftp path. But that just gives me an error system cannot find path and brings me to C:\Program Files\GPSoftware\Directory Opus :confused:

Aha think I have it figured out. I had the sitename in a subfolder in the address book so it had to be @subfolder/sitename and it seems to be working and remembering login for the tab group (fingers crossed). Man that was a trek through the unknown.
