Hi Aldiranpa,
Friend, sorry.
- Encrypted files, can only be opened with SanDiskSecureAccess.
- Read my post, carefully, because SanDiskSecureAccess is a portable app (free), easy to use and works very well.
- If the above steps have not solved the problem, and for other ideas, also you can send the question to the Support Team :

Luck.
