I'm stuck in a loop. Can't access the library at all. Can't fully uninstall it. Can't install it. The app knows I own it, but without that VERY dead HD, there aren't any methods being suggested that work. Any ideas?
Since you did not return the I will consider this issue as solved. Should however the issue persist then please contact N.I. Native Access and Installation Support .
In case that you need guidance contacting support : Please read : how to get support !
You do not explain exactly what is the problem when doing exactly what ?
From what I understand then you no longer have the content and that it needs to be re-downloaded ?
