Congratulations on the birth of your Trainz TS2010 install!
These warnings are normal and the very long time updating the database is part of the normalness of Trainz.
Here are some tips you may find useful now that your Trainz is installed:
* Back up your install, and especially your Userdata folder frequently. This is where all your downloads will reside as well as any routes you create.
* At the Launcher, go to the Options and then Developer tab and check the Show database process windows checkbox. Use these to confirm when it is safe to shutdown or restart your computer. When these disappear from the taskbar, it is safe to perform those actions.
* With this you should be all set. Have fun!
