Hi, thanks for the kind words!
I am sorry you are encountering this issue but don't really know how to help at the time being.
This is a very old project I put together more than 4 years ago and I discontinued it soon after.
The entire code base would be to be re-factored basically from scratch and I don't have the time and energy to do that now.
