I already installed twice both pack (main and Expansion, downloaded from RWA LIbrary, for test purposes) in a clean railworks installation and they are working fine. If you have PACK02 you can use only SD70ACe liveries BNSF (Default), BNSF Whisper, CN and NS. Other than that... you may have a deffective installation of your PACK02. A verifying of cache game and then a new installation may fix.
Another important note in the Readme is that some Win 7 users (version dependent) are having problems to extract (unzip) the file which causes deffective installation of 10-Engine pack (that's a WIn 7 issue when the folders' path have more than 256 characteres, usual in TS2012)). You have to extract the files using the option "Extract here", as per Manual as well.
Keep us informed...
Doc.


about only (cough, hem) compressed 9..... (cough up, choke, hem) MB thoug
That's the size including .Geo and textures, so only via e-mail indeed. Anyway, let's wait the verifying of game cache as suggested by Krellnut (deleting previously the PACK02 & 03 folders). In this case would be faster than send via e-mail such large file.


also if you gave up. I tested the pack from RWA in four different installations (the normal, one exlcusive for test, and two cleans) and didn't have any problem, so I guess the pack isn't messing the assets, unless other users are having the same problem and they are not reporting on here, which is a pitty! A good part of creation (if not the most part of it) is invested in testings, including installation's tests, to avoid problems for users.
