Hi there guys, I'm wondering if someone out there may have a solution to my problem. I have an ESI ESU1808 rack 18in/8out USB interface which I've been using a fair bit in the past for recording with Pro Tools 10.0.0. In the past it has worked a treat, but I haven't touched it for some time.

Ravenfield Esi Esu1808 Audio Interface Driver Firmware For Mac

I've mainly been using my 2.4GHz 4GB DDR2 Macbook Pro standalone for remixing. Over the past few days I've been having some serious problems, particularly in playing back though the 8 outputs. (even just 1 output) I get a -6101 error every time I hit the playback button even though I have no plugins and my Playback Engine settings are maxed out.

I know this is a common problem but I've looked at numerous forum threads and videos on how to get past this and nothing's worked. My Settings are as follows: Playback Engine ESU1808 H/W Buffer Size: -1024 Samples Host Processors: - 2 CPU Usage Limit: - 90% Host Engine not checked Anther problem is I'm not seeing any of the other options in the Playback Engine window.
