How to solve an error 42408 in Itunes (i want to keep an older version 10 because better interface )

Question

I did not like versions of ITunes after the 10.
I try to reinstall a version 10 after the 11.
ITunes 10 is now working well but i cannot anymore use Genius, and have a report of error 42408 that block the setup of Genius.
Do you have a solution for this (other than upgrading Itunes, obviously !).
Thanks for your support.

OK, my starting point is that LR can happily contain 400000+ photos, and it's a mistake to create a 1 star plus catalogue as you suggest. Instead, I'd recommend you create a master catalogue of all your photos, which you can then query however you want - 2 star, or a certain keyword, or with "xyz" in the title etc.
If you are intent on going that way, you could try a slight change from what you've done so far. Instead of trying to import an entire catalogue and then delete no-star pictures, take the 2014 and 2012 catalogues and select only the 1 star photos. Then do an Export as Catalog for these items, and import the 2014-1star and 2012-1star into your new catalogue. That may get you past the problem images which I suspect are the problem.
If that doesn't work, or if you follow my initial advice, you're going to need to identify the image where the failure occurs. You may have a corrupt image file, and replacing it from your backup may be sufficient to resolve the problem. Alternatively, it may be a corrupt record in the catalogue, and in this case it may be sufficient to remove the image from the catalogue and import it again. You might try selecting everything in the 2014 catalogue and seeing if you can do an Export as Catalog, creating a clean 2014, and deleting 2014's previews folder might also get rid of a potential problem. Something else is to try the Export as Catalog for images 1-40000, then a second Export as Catalog for images 40002-50k.
So a few things you'll need to try, rather than a magic bullet, and a recommendation to change the underlying direction.
