Monodevelop crash when I try to open a new c# file, created on unity.

I have Unity Personal 5.3.2f1 64bits on my Windows 8.1 computer, and I use monodevelop 5.9.6 which is implemented in unity. Recently, when I create a new c# file on unity, and when I open it, Monodevelop crash on loading this new file. If i create this new file on the Monodevelop interace, it works... ![alt text][1] [1]: /storage/temp/66048-sans-titre-1.png But.. I can open without problems older files on Monodevelop or Unity tree project.
