The .wps in question is attached below. The trouble is that when I open the sucker up in the Rockbox theme Editor I get told that the "Document Parses Correctly" but it doesn't behave on my player.
It's been a while since I was familiar with wps code but I think everything is in line with the new format, Please Help!
UPDATE: By thinking deeper I have found the solution: I realized that this wps (deep_sea) is just a color mod of cabbiev2 so replacing the .wps with cabbiev2 and renaming it properly fixed everything.
Still, if anyone can explain why the Theme Editor can't see what's wrong with the posted .wps please post.
