Did you add your original saved/shared folder for sharing in the new version? In LW tools > options > sharing > click Add > browse for your old folder > once you find that, click Select > Apply > ok.

I reckon it's confusing. People can add their original folder for sharing (that's what I did)...in that case there'll be 2 shared folders...the original one & the default shared folder from the new version. Clicking on 'view my shared files' (just above LW's connection bars) will bring up the shared files in LW's library. Then there'll be 2 shared folders showing up under Shared Files in the library.

Or, people can totally change the saving & sharing locations in the new version & make their sharing location the same as their original sharing location. Then there'll be just the one shared folder showing in LW's library. Tools > options > sharing is where you can change the location of the shared folder. Tools > options > saving to change saved folder location.

Or, people can simply move all of their files from the old shared/saved folders into the new version's shared/saved folders. You can't do that from within LW's library...you'll have to open the folders outside of LW & move things.

People who were using version 4.14 or older will find the new version a bit strange because the saved & shared folder used to be the same...saved files were shared by default , so there was only one folder.

Let me know if any of that helps.
