So it turns out the problem was that a file of mine was being deleted overnight.
Arena was a batch file that would run a.exe
For some reason my computer deletes it overnight. Anyone know how to protect the file?

I've never heard of a problem like this before, do you run Antivirus software? If you do, try excluding the files from the Antivirus auto-protect, maybe it thinks they are dangerous and its automaticaly deleting them :shrug:
