I tested the indicator and it loads up. I even got some alerts. The problem is that it is not drawing lines for some reason. It would take some time to go through the code and find out what's wrong. This is not something I would do for free.
Hopefully, the problem isn't in the DLL. If that is the case, nobody but the author will ever help you, because the DLL would need cracked and it would be a complex and time-consuming process. That would even be legally risky, since free or not doesn't matter to the law. I do not think the issue is with the DLL though.
