Thanks, I'll try that. I was actually about to make a correction to my above post - what it's looking for on the first computer is the fireface.sys file, which I don't see in the folder (just fireface_64.sys).... ok, I'll look at the instructions (though I've never had an issue updating drivers for the FF400 before)...

Yeah, those instructions are what I've been doing. I realized that the firefacemix file was missing from the original folder from which I was extracting the files. I must have somehow deleted it. Seems to be working now, thanks for your help! Not sure why the green WC LED isn't lighting up, though, especially having just come from being repaired. I'll see how it goes.

Thanks again,

I thought that having the FireWire hooked up to the computer and "Word Clock" selected under "Pref. Sync Ref" in the RME Fireface Settings would cause the green WC light to come on. It's been a few months since I've used the unit, but I seem to recall that one of the green lights would come on when it was communicating with the computer. Am I mistaken?

Hi there i just recently bought a fireface 800 secound hand,wasnt able to get a brand new one due to my budget at the moment..the seller didnt send me the cd with the unit....ive downloaded the updates and file from the RME website,but i need an SET UP File.so i can install the firefiace..im on pc windows 7 64 bitt.where can i download this???

Kind Regards George....
