You probably haven't setup the rompaths correctly.
Keep in mind the two possible scanmodes:

rompath\setname.zip for zipped sets
rompath\setname\file 1... file n for unzipped sets.

The (one and only) setname in the titles datfile is "titles". So you have to setup a romfolder pointing to a folder containing titles.zip (and that zip contains the png files) or you point to a folder which got a subfolder called "titles" (the setname) and that subfolder got all png files unzipped.

Example: You store the tiles zipped in D:\mame\misc_art\titlepics\titles.zip then you have to setup a rompath D:\mame\misc_art\titlepics\

or you store them in C:\temp\test\flyers\005.png ...pacman.png etc... then your rompath is C:\temp\test, since flyers is the correct setname.
