Simulator launch error

[State Thirteen]

Hi,

On win7 Eclipse CN1 Simulator just stop working for no reason. The build of win8 app was the last thing I did. After this I am getting this error:

I assume something is wrong with Simulator config. This is what I have for my project

I manage to fix it. I copied the .launch file from the new project and altered it to suit my project. 

Nevertheless it could be the regression in Eclipse plugin.

Thanks for the heads up, but I'm not able to reproduce this and we haven't touched this area for a while.

Please let us know if you come across this issue again, thanks.

Hi,

to fix the simulator all you have to do is copy the fields from the build/tmp directory into the bin directory.

and like magic everything works again.
