Sdl Dotnet error

When I open PMU,I get this error.

System .Type Load Exception: This cannot be open.
‘Sdl DotNet. Widgets. Window Manager’ from the assembly ‘Sdl DotNet, Version = 6.1.0.0, Culture = neutral, Public Key Token = 26ad4f7e10c61408’.

Go to your control panel and uninstall a program called “sdldotnet” from the programs list. Should work fine from there.

I did but I still get the error.

Still nothing??

This error should be fixed now. You will need to reinstall PMU

Yep it working now, thank you.
