Yeah it seems like it was the miner fee. I used the standard which Armory offered.... I moved it one digit to the left and I finally was able to do the transfer. Whats the usual fee I should include?
It really depends on the size of the transaction. The larger the size, the more transaction fees you should include. I would say about 0.0003BTC per transaction would be fine.
You can estimate the fee using:
