Garrysmod content not appearing to be useable

I am having trouble here. My Gmod worked last night but come today all the content on the controller in the main menu is grayed out and won’t enable.
It has a folder with a cancel sign through it and I can’t check mark it.
I can’t enable the steampipe thing.( It doesn’t show up.)
I have found someone with the exact same problem but there was no solution. I can’t uninstall anything due to bandwidth so that is not possible.

Verify the affected games. It will probably ask you to convert them too.
