i made with accept payment a address and sent there the 1000 helium i never used the getacccountaddress in the debugconsole..
Yeah that's probably the problem. You can't just skip steps. You need to use getaccountaddress in the debug console.
I show you how to do it all right here:

and no you dont need the command getaccountaddress.. if you make just a address with name MN1 in accepting payment and sent there 1000 helium its enough. getaccountaddress is like doing this.
