Is this in the Bootstrap part of RSD2? The same thing happened to me. I got the advice to delete the file SharedSettings,
C:\Users[username]AppData\Roaming\SharedSettings.ccs, and that worked.
What I actually did, was not deleting that file, I just moved it to a different location. The system will then create a new file by the same name. I restarted RSD and saw that the components were back. Afterwards I put the original SharedSettings file back, deleting the new one, and the components were still there.
The reason for not actually deleting the file is, that if you do, and are using DFTP, all your server settings will be lost as well.
Thank you so much Inger, this solved it for me too.
