Bug? Loading project

Hello my friends,
I am working on a project. Yesterday, i saved firstly all progress and then i just closed my screen, not shut down(laptop owner). Today i try to open again my project and says this attached message. All layout, services files, still exists, but does not start my project. Is there any way to recover my main file project?
Thank you for your time and wish you a happy 2017.

p.s.1 "Το δεδομένο κλειδί δεν υπήρχε στο λεξικό" means "Specific key does not exists at (dictionary)"
p.s.2 I did not closed b4a before close my laptop's screen, i just saved it before.

1. Delete the <your project>.meta file. It is not very important.
2. Open the b4a file with a text editor and check its content.

Thank you for such a quick reply, i deleted meta file and i tried to open with text editor or notepad++, it's just blank. Do you want to send you my project as zip, maybe you can save something cause i will get crazy if i have to write it again.

If the file is empty then there is nothing that you can do to get the code back except of restore it from a backup.

The IDE never writes to the file while it is open unless when you save the project.
