Different browsers require slightly different connection strings. Most browsers will successfully connect if your connection string is:
ftp://youraccount:password@your.IP.add.ress
If, upon connecting, you are only able to see the "public" folder, then your browser is probably requires a differently formatted connection string. If this happens, change your connection string to:
ftp://youraccount:password@your.IP.add.ress/youraccount
That should fix the problem.

NOTE: Some browsers may require special connection string settings. In this case you need to consult your browser help for additional information.
