Plugins no longer working

I don't know which version this happened in, but two plugins that had been working are no longer working.

The last time I'd use the software a few months ago, they were fine. But when I opened the software yesterday, and agreed to the update, it seems that they no longer function. I tried deleting them and adding them back it, but it didn't help.
