PSPICE Model for TL494

Hi,

I am designing a circuit with TL494. When I run my model in ORCAD it gives me many of this annoying error: Less than 2 connections at node. The nodes are all connected tothis TL494.

I've been told that this model is just for schematic purposes and I cannot use it for simulation. So, does anyone have any idea what I can do?

 I hope I get some answers on this question since there is not similar answered question on the web as so far I've search.

 Thanks
