'System.Type' does not contain a definition for 'GetTypeInfo' and no extension method 'GetTypeInfo'

I am getting this error when building for Windows Store...

Assets\Plugins\Everyplay\Scripts\EveryplayRecButtons.cs(392,47): error CS1061: 'System.Type' does not contain a definition for 'GetTypeInfo' and no extension method 'GetTypeInfo' accepting a first argument of type 'System.Type' could be found (are you missing a using directive or an assembly reference?)​

and...

Assets\Plugins\Everyplay\Scripts\EveryplayRecButtons.cs(392,85): error CS1061: 'EveryplayRecButtons.Button' does not contain a definition for 'GetTypeInfo' and no extension method 'GetTypeInfo' accepting a first argument of type 'EveryplayRecButtons.Button' could be found (are you missing a using directive or an assembly reference?)​

I just updated to the newest version and it did not fix it... HELP! thanks
