Add Shared Folder resetting

Hi...I'm using version 157 NS 13e and just lately it has started to delete the folders i want to share. I have 1 folder still there for my userlist but everytime i add i folder for public it resets and will not keep it? anyone got a fix for this or knows whats going wrong. I'm using windows 7 & running it with winamp & firefox only. any help would be cool. thanks for a great program!

I just unshared all my folders and added a main folder which is now sharing to all....everytime i try to share within that folder it will reset...all other folders are sharing when added...only the folders within the main folder are not!
