Train simulation software

Does anybody know in Train Simulator how you get rid of the history of a file that I installed a while back. What I mean by this is I put all of these downloads into Train Simulator and when I got kind of tired of playing Train Simulator I delete all the files from train simulator and when I tried to reinstall Train Simulator a year later it came up on a screen saying Error Reading Train Databse File. After I hit yes it went to the same thing just onto a different file. After hitting about 100 of these Train Simulator finally opened up. Can someone help me fix this problem?

Correct me if I'm wrong, but your post sounds like you deleted files instead of running uninstall.  The program thinks it's still on the computer and is cannot find the files that you deleted.

If that's the case, try uninstalling it before you install it again.

Installed programs make changes in system files, they don't just add new files.

Another option might be to install Train Store and pack everything away.  Then you can open just what you need for each run and it will only load and look for what it needs for that route at that time.

I installed the program and now I will see how it works and how it goes. If I run into any problems then I'll ask.
