This error occurs when you are submitting the wrong information, even if it is a very simple error. A transaction ID will be a string of random characters that is EXACTLY 64 characters in length. If you have missed a character it will fail, and if you have any extra character it will fail. If you are trying to submit a blockchain url such a http://clockchain.info/tx/... It will fail. 


We suggest reviewing the tutorial videos located here: https://cryptomaxx.com/page/tutorials


If you have followed the video tutorials, and you are 100% certain that you have the correct transaction ID, then please submit a support ticket and include the following information:
