I haven't yet tried a backup at this point but is this where it would fail? We can load MC11 libraries but not further back them up? Just want to check on this and get some clarification if I should be rebuilding my library from scratch.
I'm not entirely sure if this will answer your question, but the way it works is like this: You can restore an MC11 library into MC12, at which point it is converted to an MC12 library. You can now back up this library in MC12, but you can no longer load THIS library into MC11. The backup should not fail since as far as MC12 is concerned, the library is now an MC12 library. The thing you CAN'T do is use the MC12 libraries in MC11, which is why the libraries should be kept in different places if you have both MC11 and MC12 on the system at the same time.
Does this answer your question?
