Sounds like u had the flashfxp layout. Try downloading it again and put it in the path where u have your data folder path. Normally u have it in C:\Documents and Settings\yourusername\Application Data\FTPRush
Add a folder called Style and put the content of the flashfxp.rar files in that folder, restart ftprush and change to the layout flashfxp in Tools menu.
