I can PROMISE you ONE thing....
These problems you encountered have NOTHING to do with the "Theme/Skin" itself.
It concists of Graphics in a "Packed" Wba-file, that´s it. -It Can´t suddenly create this misshap.
Edit: Some event must have added/changed or suddenly "dislike" it.
Recommendation is to remove the skin completely, -Re-download & / or Do a complete Registry fix & clean up.
