UPDATE: It is now 3pm Saturday. After a failed attempt at installing P3Dv3, I tried to roll back to my previous install. It didn't work as expected, and I couldn't boot up the sim. I got CTD at loadup, right after "Generating Scenery File Indexes", with a terrain.dll error. I eventually decided to do an uninstall and reinstall of v2.4. Then upgrade that to v2.5 after another reboot. Well, I haven't gotten to the reboot yet, but I was able to load the sim, and it is running now, as if nothing ever happened. So I flew from Ketchikan to Misty's. Success. All addons and modules seem to be intact, and operational. The sim reports itself as version 2.5 already. I may run the version 2.5 installer anyway, just to ease my mind. I was sad this morning, when both of my P3D installs were broken. Now I am feeling much better.
Note to others: DON'T install version 3 OVER version 2! You'll be sorry. It is a new sim, and different enough to mess things up. Plus, if it don't work, you'll want to go fly in v2.x to shake it off. The folder names are different, there are some new folders, and some "Avatar" thing I haven't even seen yet. Some guy in a white shirt and blue jeans.
Good luck out there, and glad it is working for you Patrick. Pictures look great. I look forward to the ATI hotfix, so I can install P3D version 3 eventually.
