for that sound problem:
some options, like replay sound, should be handled carefully. if you put this rule somewhere, it will start your sound EVERY frame...
you need to make some rule construct, which activates the "replay sound" only once. maybe you can set a map flag. for example you could write something like this:
if map flag 1 is false (false is default)
- play sound
- set flag 1 true
second question:
i think this comes because the samples could be better described. for every template you import, you will have to look what things the template additionally needs in your project. some templates bring in a "ladder" tile category and work with it, but usually you will not have this category when you start your project. the solution would be to simply create a ladder category.
in this case (without looking, forgive me please), it could be some sprite parameter you need to set in the map editor.
some times you will have to look into the sprites codes. there could be rules which deal with counters that not exist in your project.
usually, the error messages at compiling will give you a very good hint. weren't there more text before your posted error message?
