Hey,
They did not give me a definite answer but it looks as though they may have been caught by banks or fbi or someone here and it sounds like they have been in the process of attempting to find a new one to be able to process checks to customers in the US that will cash without causing an issue. In regards to in progress these are the sites steps to a withdrawal:
Sent: The withdrawal process is complete and the funds have been sent to you.
In Progress: We are currently processing your request.
Pending: We have received your request and will begin working on it as soon as possible.
Cancelled: This indicates your withdrawal request has been cancelled and returned to your vchip balance.
So in progress was the last step before sent. As I am writing this today 5/20, my account has changed to SENT and it looks like I should be receiving it shortly. Hope this helps you and anyone else having an issue. Good luck
