Windows 8

In the lastest buld I tried shredding files but it doesn't work
When I hit on Shred File I get this error

Excepcion al ejecutar la operacion <<_gui>> <>

Either I click on Delete or Cancel it closes automatically

Hello,

When I try to use this option, I get a warning that it will take a long time. Then when I proceed, it takes less than one minute to finish, and I get these error messages:

Can this still be run in Windows 8. Or will there be issues? Everything installed fine, Just want to double check with the creator as a safety measure
