Some issues with using libaria2 to unpause downloads

Hi guys. I've been using libaria2 for file transfers lately, but I'm having some issues. For example, using the pauseDownload function, pausing, and then specifying the save-session option for the libaria session using SessionNew to make it easier to persist to the aria2.session file, all this is all well and good. But after the program exits, you need to pass the session object to use unpauseDownload, but the session object is returned with SessionNew, which makes sense, right? Isn't this a new session object? Using SessionNew's option there is input-file pointing to the disk file I used to output with save-session, but using unpauseDownload still returns -1, how should this be solved? Or say that the program is paused, exited, and then started the program, and I want to continue downloading [not the beginning], what should I do?
