I'm not sure, too.
Maybe Party changed something with the handhistory format.
Or parts of the hand got missed by SpadeEye.

SpadeEye is doing, what it has done before.
If it worked before I currently have no clue why it is not working anymore.

You can try to lower the value "delay between passes" under "Main"->"Options"->"General" to for example 600-1000.
Maybe this will minimize the failure rate.
