Not to open a new thread, this relates to the same issue.
I just started with Construct2 and downloaded r90 a few days ago. I wanted to publish a game on Arcade now and get the following error:
"You are not using a new enough release of Construct 2. Please download the latest release, export your game in it and try uploading again."
I downloaded the latest stable build again thinking there's a new version, but now I see it's still r90.
I rebuilt again, and still can't upload.
Any ideas what might be wrong?
