ok - the problem startet when I created the new address with "masternode genkey" and send the collateral to that address, Then the Tx was done and visible on the blockchain but up to now it does not show up in the Tx list of the Qt wallet. As next step I setup the masternode created the dash.conf there and updated the masternode.conf locally. the masternode runs now and is shown on dashninja as active. But dashcentral has some problems with it (not so my other masternode. today I checked everything again to verify the unlisted Tx and found that dcupdater (from dashcentral) shows a wrong payout address - it is the address of another masternode. I doublechecked all entries in dash.conf (masternode), masternode.conf (dash-qt) and dashcentral.conf (masternode) - everything ok what could be the problem?
