Help with AES 128 encrypted file

I'm trying to decode a file encoded with DEC 3.0 library (Delphi Encryption Compedium Part I).

The key is a SHA256 hash:
HTML Code:

It's croped to 16, to fit the maximum 128 key size.

No matter how I try, I can't decrypt the file.
I know that its a simples XML file.

Looking into the code, I suspect that it is using:
CTS Cipher Text Stealing, a Variant from CBC, but relaxes
the restriction that the DataSize must be a mulitply from BufSize,
this is the Defaultmode

The encrypted files are here:

Does anyone have a clue?
I can use any high level language: C#, Delphi, PHP, Python, Perl, etc.

Key can be unicode, include trailing 0, plaintext can be compressed etc etc.
