Remove expiration date from software which isn't updated anymore -- 2

It's written in C++ according to other freelancers on this site (see C++ image, attached). The software can't run because it's past the expiration date, 01 error attached below. If you change the date on your computer and try to run it, you the 02 error message attached below. I'd like someone to find and remove the expiration date part of the program so I can continue to use it. The original programmer stopped updating it and removed all the websites and everything related to it. I don't have the original source code or installer, just the latest installed files (attached)
