Hello I have modified the custom parameter of "call history" to a higher value of 365, because the default value was way too small. The program accepted the change but when I tried to move to another settings section, I got the error: "The specified call history interval is invalid. Please enter another one and try again" The problem is that if I go to "Advanced/Custom parameters", the list is empty and I cannot modify the required value. Nothing is being displayed because of the error above. Is there any file containing the settings for "custom parameters" I can manually modify? For the record, I did read the "warning" about not messing up with those settings, but never crossed my mind that the program does not have some built in "stupid prevention" If the value is not in the required range, it should give the error when you try to hit "Apply" not after.
