As the title says I bit the bullet and upgraded. No problems with the patch either way, about 2 hours for everything to load. Now for my questions: how do I fix the wav files? A lot of the items that are loaded into covered hoppers, tank cars, boxcars, bulkheads, etc. have to be upgraded. For instance: Potash - kuid2:30671:9283640:1 needs to be 9283640:2. Do I have to make the changes or does the game take care of that? I really have a lot of changes to make along those lines. I haven't even gotten to the locos yet. That might be another nightmare. Any suggestions or thoughts will be appreciated. Thanks.
