Error while opening the GDL source

[Anonymous]

Hello,

I am new to ArchiCad.
Every time I open my main project, I get this error dialog. The first line in the report is : "Error while opening the GDL source at line 0 of file MASTER_GDL.GDL.txt."
Unfortunately, I cannot find this file which seems not exist.
Is it possible to rebuild this file ?

Many thanks for your help,

Best regards,

What libraries do you have loaded?

It appears that you have a master GDL part that is looking for the file and can't find it - thus the error at line 0 (otherwise errors occur at actual line numbers). It may be of no consequence, depending on whether the master GDL is actually doing anything.

Thank you.
I have loaded the standard libraries.
I forgot to precise that I am using ArchiCad 8.
It seems indeed that there should be no consequence but error messages make me nervous.
I would be happy if I can restore the file.

You should at first upgrade to AC 8.1. It is a free upgrade.
It may solve your problem.

Thank you, Laszlo.
I already have the last upgrade, 8.1 R2.
