decrypting an AES-256 zip file created with Directory Opus

Hello. 

I can't code. Attached is a zip file created with DOpus. Only 7zip and Dopus can decrypt it. Windows Explorer cannot. I found no program that could crack it. The password is "mmx". 

Is there an easy way (for non-experts) to crack it?

Thanks.
