I will explain you this one last time. The files that were not subjected to modification during the encryption process by your security software were decrypted by you without any problems. The files that were damaged by your flawed security software during the encryption process are the ones that are now corrupted. Contact the company that provides you with security software to solve this problem. As soon as they make the files the way they should be after encryption, you will be able to decrypt them using the decryptor that you already have.
