It looks like you modified the ubb_unregistered.tmpl file so that you have only two table rows instead of the three that I scripted -and with those changes you would have to change the class of the first table cell to menubar and you'd have to make the last table cell span two columns...
I walked the scripts that I have for those two files and they both work fine without any changes. The concept is to have the user name, logout / login text, and PM notice on the top table cell / row with tdheader as the class. The middle table cell / row contains the forum menu with the menu bar class, and the last table cell / row contains the tdheaderb class and it's the same color as tdheader. Three rows, one cell per row.
To get the full effect of the design try making the background color of tdheaderb the same as tdheader. Or better yet: make a gradient for both using the same color...
