If you see that everything is loaded into the correct folders, then maybe you need to check if the train is the correct one.
using windows explorer, go to
C:\program files\mackoy\bve4\railway\route\your route
find the \your route.csv file then right click on it. Depending on your version of windows and the way you have it set up there are 2 ways to look at the file.
1) right click on the .csv file and choose edit
2) right click on the .csv file and choose "open with" and pick notepad.
look near the top of the file and look for a line or 2 that looks like this.
with train
.folder cl323
see if the .folder cl323 matches exactly with the train folder that is on your computer.
c:\program files\mackoy\bve4\train
If the names do not match, let us know, and someone will be glad to help you fix the problem.
Just don't panic or give up. There is a simple solution.
I will not overwhelm you at first, just remember, you will be a BVE veteran soon.
