When I am attempting to reserve a name using the command:

namecoind.exe name_new d/

I keep getting this error... error: {"code":-4,"message":"Error: This transaction requires a transaction fee of at least 0.005 because of its amount, complexity, or use of recently received funds "}

However, I have more than .005 in my namecoin wallet, that I am attempting to register from. I have .01 in fact.

What is going on here?
