VST content not loaded and details not available

While loading C11.0.40 (and .30) the sounds I ha downloaded and added to library were not accepted, prompting this message:

when seeking more details, the site is not available.

So, I remain mystified. If anyone knows why these sounds are not accepted I would be very grateful and pleased not to have to speculate on when service might be available!!



These are dedicated libraries, you would need to buy the license.

Thanks for that Martin.
Even though I had a suspicion that this might be so, I thought the information supplied to the user was far from helpful. As for the Service Unavailable message, well that is just too cryptic for words!
