Missing .lib files?

Hello,

I'm trying to simulate a fairly simple two-BJT amplifier, which uses MPSA18 transistors, which I found with the "transistor.olb" library. When I try to simulate, though, I get these:

WARNING(ORNET-1119): No PSpiceTemplate for Q1, ignoring

WARNING(ORNET-1119): No PSpiceTemplate for Q2, ignoring

I suspect this is because there is no corresponding "transistor.lib" file in my C:\OrCAD\OrCAD_16.5_Lite\tools\pspice\library folder. In fact, there aren't nearly as many .lib files as there are .olb files.

Is there somewhere I can find the library(ies) I need, or am I doomed to a limited number of models since I'm using the Lite version of Capture? Or am I having a completely different problem? Thanks a ton.
