Well I am guessing the last one.
I go to the address
Enter your Ether address
Copy/Paste all the text I receive from the link, this opens in a browser for me, I could post it if required.
Click access.
I select withdrawal from the drop down menu.
I open my wallet file.
I enter my password.

Now the 'write' button appears. When I click it, I can't send Ether. But don't understand how to withdraw.

Also I hope I can withdraw partially, not all of my investment.
