Now the not so fun part... since your Carrara inst seeing your content you will need to add all by hand (you can try to reset your preferences to first: go to MENU / RESET PREFERENCES), just after copy all stuff to the right place.
O add folders by hand you can go to the Browser and in every tab you just click in that small black button and choose ADD FOLDER.
You can see a lot of tutorials about Carrara here:
