SanDisk secureAccessV2 restart loss of encrypted datas

Hello, I would just to ask. I have a problem regarding to my usb vault, days before I open my usb vault V2 I was able to see my encrypted files but yet days after, my usb suddenly asked for another new account for the vault and afterwards I was unable to see my last encrypted datas. Can I ask if there’s any way to recover it again?

I suspect someone tried to access your files and used up the wrong password limit.  I think your files are lost.
