I recently purchased a book from the Pleco online website for a Mandarin Corner reader and even though I used the same email addess, I ended up with a new Registration ID. Now when I update my Pleco, it only has the new purchase for that Registration ID. My previous purchase of Outlier and other addons are not there. If I wipe the Registration ID and enter the old ID, the Outlier is available to download again, however next update is the other way around. Outlier with no Mandarin Corner purchase. If I purchase another book via the website will I end up with a third Registration ID? Is there anyway I can merge my two ID's into just the one?
