getCpuUsage not working

[wisemike2]

I downloaded the latest version, but I get the following error, and I don't know how to fix it. Any suggestions?

getCpuUsage(): couldn't access STAT path or STAT file invalid

This is my server's info:
Operating system: Linux 4.10.0-35-generic

Try on windows, if work, is a linux only problem.
