Hello.  I bought a .dll file which came as X64.dll and X86.dll.  It came zipped, the program to which I imported it auto unzips and runs it.  The file works, but I want to add a small fix to improve it.  I would not change the code at all, simply adding a signal or alert to it.  The seller will not talk to me about my idea; they sold it, now they're done.  How can I see the code to accomplish my task?  I believe it's all C#.  At the very least, how can my computer see the numbers that appear on screen (which I do not want to change in any way) so I can perform simple, real time calculations to those numbers?


Thank you.
