Empty vault

Hello, i have a problem with my Cruzer Blade 64GO

I opened Secure Access 2.0 today after not using for a while.It asked to check for update and then updated.

On opening V3.0 it declares my files are not compatible and need to be upgraded, i removed then V2.0, but still the same message.

I download V2.0. and install it again

It installs as for the 1st time and prompts for new password which i define the same as the old one.

On opening no files are visible, even if in the vault folder, there are lot of files with .dat at the end.

Can someone help me to fix this problem, it’s about 20Go of important files.

Thank you.

even i have the same problem any luck
