This hack (which I'll offer more detail here on how to do) works for many different miners that are "locked" to one pool:https://bitsharestalk.org/index.php?topic=1921.msg22358#msg22358
My instructions here assume you're running Windows (maybe Windows 7). If you're on another platform, you'll have to look up how to modify the hosts file for your platform and/or otherwise redirect inbound/outbound traffic from a particular IP address.
First, shut down your miner (if it's running). Then navigate to:
--and double-click the file which is named "hosts." Windows will probably ask you what you want to open the file with; choose any plain text editor.
Then edit that file so that the operating system's networking redirects all traffic related to one address to another address. For example, if the miner is hard-coded to mine at 188.8.131.52 (I think that's beeeeer.org), you can add this line to the hosts file:
--and then save the hosts file. Then start up your miner again. Voila! Your miner mines somewhere else.
