Sorry to hear you are having issues. If it only happen to that theme than most probably, yes, there is something wrong with that theme. I have similar situation when I am trying to load my very old theme like Sonix.wba. Last updated 2000.
You will need to look into all the parts in that theme and see which of it is giving a problem. It will take a lot off time.
Or, The best thing I would do, is to rebuild it all over again. You already have all the graphics parts, you just need to rebuild it from a known working theme.
Just a suggestion.
