SQLite3.dll Can't be Loaded!

After being away from autoit for a while, I've picked up an old project again, but run into trouble when trying to use sqlite.dll

On running _SQLite_Startup(), I get @error=1 (Call Prevented by SafeMode). It does not run with _SQLite_SafeMode(False) or _SQLite_SafeMode(True)

I thought SQLite3.dll could have been overwritten in @SystemDir by a 3rd party app (thunderbird or other), and I replaced it with the file in http://www.autoitscript.com/autoit3/files/beta/autoit/archive/sqlite/SQLite3.dll in an attempt to fix the issue, but I think I could have made things worse. I did unblock the dll btw.

Any thoughts on how I may fix this? I'm running:
>"C:\Program Files (x86)\AutoIt3\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.exe" /run /prod /ErrorStdOut /in "F:\db.au3" /UserParams
+>02:16:43 Starting AutoIt3Wrapper v.2.1.0.8 Environment(Language:0409  Keyboard:00000409  OS:WIN_7/Service Pack 1  CPU:X64 OS:X64)
>Running AU3Check (1.54.22.0)  from:C:\Program Files (x86)\AutoIt3
+>02:16:43 AU3Check ended.rc:0
>Running:(3.3.8.1):C:\Program Files (x86)\AutoIt3\autoit3_x64.exe

Thanks, in advance for any help you may provide.
