When I tried mange conversions in ACP, I have this error.

 

OutOfRangeException:  (0)

I would recommend submitting a ticket so we can look at your site directly.

This was identified as a bug, and a fix will be coming in a future maintenance release (just in case anyone else stumbles across this). Note that this only affects older conversions and not recent conversions.
