Same question. I tested it. No this does not fix that.Question on potential uses of this:
I got official themes.
Then I pirated some theme (some that I installed were official theme i already had)
Going into Eshop removed all my pirated themes (including theme I got officially, but then installed pirated version)
Tried to go to theme shop to redownload my official themes, but I get the gray out button "Already owned". I assume this is due to the tickets leftover from pirated version.
Would this app solve that problem?
