Can you be more specific? As in, what do you mean by "they don't look like anything"?
My best guess is that you are using the wrong numberings for each style... The generally accepted style numbers are:
0: Original Dirt style
1: Original underworld style
2: Original Pink tile style
3: Original Yellow Columns style
4: Original Crystal style
5: Oh no! brick style
6: Oh no! rock style
7: Oh no! snow style
8: Oh no! bubble/tubes style
9: Holiday Lemmings style
If those are not what you are using, you need to re-name the style files to match those.
If that isn't what you meant, please clarify a bit.
