Thanks (tobi) for the help. Now i solved the problem. The is not related to gambas. String manipulation was incorrect in my program which resulted the error to look like the "subject". Also i understood the power of print for debugging / tracking errors.
> Print Error is False for both if statement and file.load function. I have checked file permission and it is root. I think file permission is not an issue here since it does not even detect file. Also i have tested the same with other file (root permission) and it works perfectly. Again i need not have to edit the file.
wow, mail citation gets weird now.
could we quickly recall? to clarify things to me, too... this all works as expected (gives True):
