Hey every one !

I am currently using a Mac Pro 2008 on Yosemitte OSx 10.10.5
But I can't find the right driver or even the right firmware to turn my FireFace. It must all work in 64bit I tried several techniques but for the moment none worked ...
And my FireFace Flash Update doesn't start : " no fireface driver or device installed." but i install the good one with the good firmware version
Which one does he have the same problem?
If a moderator can help me please:((
