If I can fix the bug so it doesn't crash anymore, I can leave it on at night.
If anyone wants to lend a hand on fixing, I would be thankful.
I'll make a topic in Help when I get the error again and debug it with Visual Studio.
It will be called something like "Memory Access Violation 0xc0000005" (because that is the error I am getting)
So the bug has been fixed.
This thanks to DogboyG and TJ.
So the server should not be crashing any more.
I intend to keep it up for tonight.
Hopefully I can fix my other computer and host from there again, then it should be 24/7
