Can't find my old post?

[Koyuncu]

Hello, 

I tried to find one of my old post trough User menu "Find all your threads" but it failed. I used Search option and searched my nickname still failed to find the post that I look for. Is there any loss in forum or am I doing it in wrong way? 

The post that I am looking for is about French translation of two passages. 

Thanks in advance
