EV11 - W2K12 - FSA - Evt ID 6481 - Unable to archive anything

Hello here,

I just create a fresh install of Enterprise Vault 11 on a Windows 2012 server. The installation process worked well.

But i'm unable to archive anything, the process report 0 file matched..

When i'm forcing the process, the following error appear in the event log with the event ID 6481:

Error accessing Vault Store.

 [Internal reference RA/GS]
 [VaultId = 1E1B6EB13005793449B4E2FC1B873525F1210000archiveciml]
%3 

I also run a dtrace which gave me the following error :
