Can any one help me with masternode?

Hello all i am new to the crypto and mining world. I am trying to set up a masternode for kingston i am using vultr as my vpn service and i got that all set up, My ip and port are open. But when i try and start my masternode from the wallet i get "Failed to start masternode Error: Could not allocate txin then show my "tx id" For my IP:9211. i have tried to create new address multiple times sending exactly 5000kgx to them and still getting same error also even deleted my wallet and start fresh. My protocol is -1 and status missing also it seems when i edit my wallet and masternode config files my masternode doesnt show up unless i reset the wallet. and when i reset my wallet and go to debug console and type in masternode gen key its differnt from the one i get before the wallet restart. Thanks for the help
