When loading ReefMaster 2.0 I get the following error.

Activation failed with the following error: CoInitializeEx Failed. Re-enable Windows Management Instrumentation (WMI) service.

I have checked my WMI and all seems fine.

This indicates an issue with the Windows installation and might require a bit of work to fix.
What Windows version are you running, and is it 32 or 64 bit?

Please try the following and either post results here or send to This email address is being protected from spambots. You need JavaScript enabled to view it. :

From a Windows Run prompt (WINDOWS KEY + R), type compmgmt.msc

This will open the Computer Management window. Under "Services and Applications" there should be a heading "WMI Control". Please right click this, select Properties and send me screen grabs of each tab within the properties window (you can screen grab to the clipboard by pressing ALT + PRINTSCRN).
