Cadence Orcad 17.2 library for ATMega329P

I have been unable to find this library in the
*.OLB file format. I found it in the *.xml
format but can't get it to work. I imported it but
am unable to access the part. I suspect it has something to do with a config file. It came with a . epw file and a text file, neither of which I know what to with. Does anyone know where to get a *. OLB file ? I know how to add it becsuse I was able to add the -AUR version of the ATMega328P but the pin numbers are different from the 28 pin DIPS I have.
