PR:BF2 launcher stopped working after installed

[SEXY1111]

I was installing PRBF2 v1.4 via official torrent,when I finished the installation and starting the launcher,it stopped working after shortly appears on the screen,and visual studio just-in-time debugger only shows up "An unhandled Microsoft .Net Framework exception occurred in PRlauncher.exe[XXXX(Random numbers,I got 3772,7276,7112,3388...etc)]"
I tried some of the method on the forum and internet,like:Using the Microsoft's .Net Framework repair tool,re-install the .Net Framework 4.5,re-install the whole game...etc but none of them work,so I think asking the PRBF2 support team should be a good way to solve my problem,thanks.
