AREX error when performing "reinforcement code check" in revit 2014

[jayallan]

 i keep getting an error when performing "reinforcement code check" in revit. in short, revit fails to transfer data to robot. i've tried reinstalling revit and robot 3 times already. also updated dotnet. not sure what to do next. tested this with new clean projects. i searched the net about it but only found an old topic for version 2013 that was not solved : http://autodesk.lithium.com/t5/Revit-Structure/Problem-with-sending-data-to-Robot-using-Reinforcemen... . any help on this will be much appreciated. tnx.

 

here is the complete error message:
