Yes I think I will do something like that ! How and I need to add something about the problem. It does not happen all the time ! Sometimes I'm able to compile it well and everything is fine. So i'm happy and i work on my map until it doesn't work anymore ! Awfull feeling when you really want to test something and you can't. And i've runned a test btw. A simple map that I compile : It works. I didn't change anything a all on the map. I just recompile it one more time in the exact same way, and guess what ?! doesn't work anymore!
Now i'm actually on a little map i'm doing and it works ( for now ! ) I hope it will work untill forever but i'm not sure about it. I will tell here when it doesn't work and what was my last change etc...
