iProtector - How do you unlock files?

I just downloaded the trial and tested it with a file. Now I dont understand how to unlock it! I must just be missing something.

Has anyone else used it and knows how to work it properly?

Many thanks.

Try dragging the locked file back on iProtector, enter the correct password and press start.
In the side drawer that opens you should see under the task column, Unlock.
