Add campaign or Add test buttons in CMO interface, I'm getting the following error: "Object reference not set to an instance of an object."
We have seen cases where doing a reinstall gets the user around this error.

I also tried to reinstall it, but didn't succeed

Which CMS 7.5 version are you using? Right-click EPiServer.dll in the bin folder of the site and in Properties check the file and product version in the Details tab.

I couldn't reproduce this issue with the latest CMS7.5 patch and CMO7.5 http://world.episerver.com/Releases/EPiServer-75--update-28/
Have you updated CMO to the latest version via NuGet?
