I am having trouble to set my Dropbox account so that it can hold custom data file that QC can use.

When I try to build this code CustomDataNIFTYAlgorithm.cs using the original Dropbox file locations it backtests OK, but when I try to put the very same files in my Dropbox account, the engine doesn't seem to find them.

What Dropbox setting should I make so that I can use my own Dropbox account?
