Hi, I think a found a bug (JSONtext-22.214.171.124). The pretty print for 2D-DBL-Array is not working correctly. There is a wrong wire connection in "Variant to JSON Text.vi", see screenshot.
I also have used Win10 in the last 3 months during my current project (LV2014 & without IP Builder). I had no problems generating the bitfiles in the Cloud, but the local compiler got stuck somewhere in the synthesis or mapping.
