The vampire sets were originally released as a free download on my website (they're one of the first freebies I released! - http://finalbossblues.com/timefantasy/freebies/evil-transforming-vampires/) The lava was likewise originally released on my website, but it should be on the master "water" set with a 100% size. If you don't have that file, email me.
Here's a 100% version of the vampire chars I quickly put together for you: Vamps
As for the char1 set; those characters are exclusive for use in RPGMaker and weren't included in the "general license" version of the pack. If you're missing those sets and you're using RPGMaker, send me an email and I can give them to you.
