Modelsim Instantiation Error

I am receiving this error  

 

Instantiation of 'DFFE' failed. The design unit was not found. 

 

Some sources are telling me to manually add the primitives library in modelsim. Others are saying that if I am using nativelink, then I should have no problems. Well I try to manually add the library in modelsim. Simulate -> Start Simulation -> Libraries -> Add -> <Quartus installation> -> EDA -> Sim Library. However after adding it the OK button is grayed out. 

 

I am running modelsim from quartus. So I presume that is through nativelink no? 

 

Anyone know how to fix this?
