Python / Visual Basic cross platform fix.

I have a small Visual Basic program that does a private API call to a website and uses SHA512 Hashing with an API Key and a Secret. There is a working Python application available but I am struggling to get a response back from my VB app.. Just getting "Error : Invalid API \/ Secret Pair ". The Python application is located here [login to view URL] The VB project is attached. You can get the API and Secret from the VB project. I expect this should be no more than a couple hours work for someone who knows both languages as they can simply debug the Python app and see what needs changing in the VB app as it's not very big and already contains all the code to perform the operation. I just believe that it is not configured correctly, debugging through the python app and comparing it to the VB app during the Hashing should give an indication as to what is wrong. I have tried importing Python in to Visual Studio but I can't seem to be able to debug it as it does not work in the same way as VB. Please only bid for this project if you have looked at both projects and are confident that you can fix my app, I am busy and it makes more sense for someone who knows both languages to fix it than for me to learn how to use Python.
