I am also mining 42coins in http://42.cryptopools.com  I have had my payment address changed on me 2 times now and can't get an answer from them.

All of my coins are being sent to other addresses and the only conclusion I can come to is the admin is changing this himself.  How else could it be changed without knowing my email, password and 4 digit pin number?

If not I hope that he can provide an explaination and get my coins back!
