Ok, kwaddd1, let's see if i can give you some answers. There are actually many questions in your post and some, to be honest, doesn't make too much sense to me.
1. Is not too rare to "lost" all your cards once in a while. It's very common that the servers here are working slow or that are completely down for some hours. If you initiate or update the program when the servers are down, the rights fail to update and your collection disappears. It this happens, it will be back as soon as the servers are up again and you restart or use the check for news feature.
2. Subscription works this way. You get a random card delivered to you everyday. Yes, the card is a full show that includes all the nudity levels available for it.
Unless you inhabilitated any of the download features, the download should start automatically for each card, every day, at the same hour, your time.
3. I don't get the 15 seconds thing. Sounds like an incomplete or corrupted download. Try this:
If the card is grayed out, the show was not downloaded and you must download it.
If the show appears to be downloaded, but it is not working, erase it and re download.
If the show appears to be downloaded, but you can only see one or two clips, it was only partially downloaded and you must erase it and re download it again.
Be sure that you have all the nudity levels selected.
4. All the shows, regardless the way you got them, tickets, booster packs or subscription, have the same structure. They are divided in short clips. There's no way to see them as a movie, cause they simply weren't filmed that way. You can only select, for instance, nudity levels, to see a show from non nudity clips to the explicit behaviour, but they will come in a random mode nevertheless.
There's an aplication that the user Wyldanimal made that let you select the clips and watch them in order. Here's the link to that thread:
