... nevermind, I guess. I opened some of my files with no problem. I also tried new ones with success... my bad, sorry.

Rodolfo,

I received a similar barrage of error messages when I first opened NodeBox earlier this week. I then discovered that this happened for some files but not for others.

The problem, in my case, was that some of my files included the experimental mouse node. These files work fine as long as you have enabled Device Support for experimental features in the NodeBox preferences. But if Device Support is not enabled you will get error messages similar to yours. Could this be what happened to you?

The solution is just to leave device support enabled. You may have to reset this (and relaunch) every time you download a new version of NodeBox.

It would be nice if the NodeBox application would check for this common problem and provide a more helpful error interaction.

Hope this helps,

John

yep, it was probably that. I did recheck the device support after the error and it didn't displayed the errors again.

It seems the error happens when there are no nodes on the canvas. I'll make sure to add a check for this.
