Today I withdrawal 0.01 KMD from the balance of the exchange, but my address (RMmkwa9pqB4LutmgZai1GAEs2ikGqzAAZk) was not come any KMD.
Please anybody can explain the reason for this problem?
My KMD I bought at cryptox.pl exchange in February, so KMD hacking could affect them or...?
I must to tell about my problem to KMD devs? Who can help me get my KMD back?

Cryptox is sending back your KMD in such cases trough BMCode. Check Myaccount->BMCodes click "use", in some cases you need to relogin to see the code.
