I tried it using my laptop and received the same error that I encountered on my PC. I think the problem may be caused by the way I have my B4A development files configured as I use Dropbox for all my libraries, projects, SDK, and Java components. Normally, this works very well where I can works on B4X projects either from my office PC or on the road with my laptop but may be causing a bit of confusion with the B4X IDE. I'll reconfigure it as see if a get the same errors.
