Homeseer Mobile Not seeing any devices --> Error in log about JSON

[sonyrules]

I am new to the Homeseer software (started using it today) and i am playing around with the mobile client, but when i log in, It says there are no device available. I reviewed the logs within Homeseer 3.0 and i am seeing an error stating "Problem serializing data for JSON request: Could not load file or assembly or one of its dependencies."

I have looked through a few settings but nothing is standing out, I am currently only using the z-wave plug in, and i have 3 devices currently. (2 homeseer and one binary switch). I did read that sometime unknown devices can cause issues. I had one of those listed, but i have removed it (home -> name -> delete)

Below is the message board system profile for anyone that can assist.
