Progline web editor?

Question

CMS

They asked for help with the site of the regional council. They installed progline for ease of editing, and now they can't change the password in it. The bottom line is that the password is embedded in the exe and it is checked against the database. Of course, I'm now being bombarded for an easy question, but no. He hid all his data in the database and I have a bad idea how to change them. Does anyone have any ideas or experience with this devilry? The problem is that to re-roll everything, not the vario needs a key, but the key costs more than my salary. How do I change the password on it or how do I reinstall it?
