TM Load stands for Task Manager load meter. That option uses a Windows function similar to what the Task Manager uses to calculate CPU load. The best method for Core i CPUs is to un-check this box and use the original method based on CPU C0%. TM Load is designed for Core 2 mobile CPUs that go into low power sleep states at idle.

I have no idea what you did and no idea why it doesn't work anymore. I've never seen this problem before.

Here's the latest version. It has a couple of more minor features like better system tray fonts so you might as well try it even though I doubt it will fix your problem.
