Ended up going back to 3.51 driver and it works fine.
Send an email to Jonathan Monroe at Actual. Let him know what is going on and I'm sure he will help you sort it out. Also, in general, while I am a Mac fan, I find WIndows to be a better server platform when having to deal with ESS, especially Oracle and SQL Server. FWIW. But if you have to run on the Mac, the folks at Actual are very helpful with driver issues.
