Quick question

Also, what are the chances of the memory leak issue actually affecting me?
Is it even a problem on modern systems, because the game is kind of old now correct?

A memory leak is not like a virus or anything. It might cause your system to appear low in the physical memory dept under extreme circumstances as long the offending process is running. However even while it is running virtual memory paging would probably not be noticeable unless you're already strapped for physical memory.
