Makefile.win [Build Error] with DevC++ while moving the project

Question

Heya,

I always got this problem, it's not a big deal, but is very boring, maybe u can solve it :P

When i make some program at school, or away from my computer, i save all the files in a USB, then i get home and i open the .dev file, but when i try compiling it, there is an error:

C:\Users\Nico\Desktop\Program\Makefile.win [Build Error] [Program.exe] Error 1

So the only way for make it work is to copy everything from the .cpp to a new project.

How i can solve this ? :D

Thanks you!
