I tried to sell two of my accounts today and did not succeed in either case.  I got an error message saying that I tried to change something I did not have access to.  

I signed my withdrawal address using my Blockchain.info wallet and I think I followed the instructions correctly.  Anybody else have problems recently?

/edit:

Here is the error message:

The change you wanted was rejected.
Maybe you tried to change something you didn't have access to.
