Bug? Error when opening a project

[Brad]

I created a small simple project yesterday and when I tried to open it today I got the attached error message. After I dismiss the error it then opens up the default blank project. I've used B4A since version 1 and never had this happen. I'm using 4.30 and Win 8.1. I can open other projects so it's something with this one. I can easily re-create it but I'm worried it might happen to a more complex project.

After creating this thread I attempted to open the project once more and discovered that it had selected the correct libraries but the code window was the default blank.

Open the B4A file with a text editor and check its content.

It opens fine with notepad++ and I'm able to see all of my code.

Can you upload the project?

Found the problem. The bad line in the b4a file was: build1=,brad.wifiscanner instead of: build1=default,brad.wifiscanner. For some reason 'default' was missing.
