The game exit to desktop before even starting!

[Desperado Outlaw]

Hello, I've been playing SS 6.4 for a while, last time was yesterday, and everything was FINE.
Until today I start the game, and it crashes to desktop. Now I'm pretty sure that when I installed it UAC was off. Also I installed in different hardware than C:\, so it is not in program files.
Today just before I start the game I opened a file called "export_descr_unit.txt", I don't if I added something but I don't remember doing anything in it, I was just reading. I may have used the "Ctrl+F" to search in the file, but I don't remembered changing its components.

Here's the log :

ok... I knew what my problem. By mistake, I replaced my descr_projictile file with one for another mod BC 2.3.
So if anyone can upload to me the clean two file (descr_projictile.txt) and (export_descr_unit.txt). Both are corrupted and I need them please. I will appreciate that from you guys.
