After apparently downloading the Z patch I read the UNlOck bottom right hand corner instruction but the next page only reads, "The program was unable to connect to the master server..
1.You may be protected by a firewall it may have blocked the connection.
2. It may be temporarily impossible to connect to the master from the isp.
3. The master server may not be running due to a technical problem.
Check status of master server.

Is there anything I can do to rectify this. I have come up with this over a dozen times now and have not been able to run LFS with the Z patch version so far..

Is your firewall maybe blocking the master server?

I had a problem with it too, I had a few caps in my acct name, so I tried typing it out all lower case, then it worked. There's definitely some kind of bug, only affecting few ppl I guess.
