First, do a 'search' on your machine for the files... Just try a search for any file the name of which you for sure remember...
Hopefully you will find that your files are not actually
deleted !
Second, have a read around the LimeWire Forums...
There are megazillions of posts here from people with exactly the same sort of 'lost files' problems !
If your files have NOT been deleted, you'll certainly find the info you need to recover/move/rename the 'missing' directory.
If all that fails
be sure to come back and you'll get more help, OK ?
