yo!

i had the same problem, to sort it out though!

here's what i did: i opened up my 'nuke DB' in phpMyAdmin and found the nuke config table (1/2 way down the list).

browse it, and find the default theme entry and change whatever is in there to: 'T-Platinum' and OK/ save it, when you refresh your site it should all be ok!!!

FYI Im having problems finding any Themes that work correctly!!!

hope that helps!
