Shawn,
Sorry, sometimes things fall through the cracks. To be honest I probably wouldn't have been able to offer much assistance. My 60D is working just fine as is my 6D and we don't have a 70D to test with. I likely would have recommended attempting to swap out the EDSDK.dll that was shipped with BYEOS to see if that addressed the issue.
Glad you got it working.
Thanks,
Jared
