Arf, sorry to hear that.
That’s all I did.
I have to mention that I restarted from scratch: from the “unzip the source”
The doc mention that if you make changes to various sdk you have to “regenerate project files” this take care of dependencies.
Starting over is safer. (even if it takes a while). Rebooting after any SDK install is wiser too.
I don’t see other ways I fixed it though. (I did spent nearly 2 days trying to fix it… and did)
