i didn't change the .dat file. i just downloaded and installed the newest wallet. then just now i noticed the wallet address on supanova was different to my wallet
i just updated the address on the pool and now i'm receiving coins again
I can confirm the same thing happened to me (and on suprnova.cc). I have a backup of my wallet machine and went back and checked, it has the same address before the wallet upgrade as after, this means suprnova changed it to
FiLso7rD92gHykCtVc1ceL9d438xptbnNT. There were not any logins on my suprnova account since the 9th, I don't want to jump to conclusions but it might be some hack or a mistake from suprnova admins?
For me the address changed around 16:28 gmt on the twelfth, I kept on mining to the wrong wallet until this morning

Update: I also had a limit of 10 fresh before payout, after the address changed it got down to 1 fresh. This is in other words not a fresh issue but a security flaw/bug at suprnova.cc.
