I had the Microsoft Rdlc Report Designer installed on my project and it was working ok. I had a problem and the program slowed down the I got a Yellow band on the top of the project body below the toolbars. it ran from side to side. It said there was a problem with Microsoft Rdlc Report Designer and gave me the option of ignoring or disabling it on the next restart. I mistakenly said disable it. Now I have no idea how to get it back.
I tried to reinstall but it said it was already installed. I have one more report to complete on this project.

How do I fix this?

Thanks in advance
