Can't use Crypto

This english section.
I used crypto version from AMS Power Pack (http://www.amsspecialist.info/viewtopic ... 44&start=0), but i have some problem with it.
First, it isn't use one time with Dialog.FileBrower, but i can skip it
Well, now, i use a new crypt but isn't return Encrypt or Decrypt string, it return only the key secret.
examp: a = Crypto.AESEncryptString("a","01234567900000100200"));
and it return: "01234567900000100200"
well, 1 month, i don't use it, and now i continue use for get data back and i can't get my data :))
