Neither Board Manager or Library Manager work?

Have tried to use 2.11 but the Board Manager and Library manager do not work. Stupidly I removed the earlier version that worked great! Any suggestions. Using Windows 10.

I was cleaning up my hard drive and got rid of many files from trying Visual Studio and Platfomio with Atom. I want to learn more about the process.
All good now. I saved my libraries and sketches. Deleted everything and started over. Ver 1.8.16 and Beta 2.11 all functional.
Thanks for responding! Since I didn't record all that I deleted I'm not sure if you could have helped me!
All has ended well with a lot of rebuilding!


I'm glad to hear it's working now!

Thanks again for responding.
