Hi there!
We have a full manual for them here:
https://kittycats.ws/manual/article.php?id=63&oid=37
A good tip to remember is to make sure that the prims are stretched low enough for the cats to bump into them. Sometimes the physics of objects can also prevent the cats from bumping into the prims so you may need to turn whatever object the Jump N Play prims are covering phantom (do not turn the jump n play prims phantom)
As for redelivery, you can file a support ticket with your transaction details where you purchased the prims and we will get a replacement to you!
You can use the Lost Password button on the log in page to reset your password, or you can auto log in using any of your cats Online Help button, a Cattery dock, or the website terminal in the lobby of the store.
