warning message not removing

I receive this message and can’t get rid of it.. (otherwise, everything seems to be working)

“The plugin Drop Down List Field for Gravity Forms requires Gravity Forms to be installed.
Please download the latest version of Gravity Forms and try again.”

Everything is installed and up-to-date. I also deactivated, and reactivated both GF and this plugin but still no luck.

Thanks
