I got it working completely (including tasks). Here's how I did it:
I first ran SyncClean in Support/PocketMacSyncManager/Additional Tools. You need to click both "Clean SyncServices Files" and "Clean PocketMac Files."
I did a uninstall using an app called AppDelete (
Reggie Ashworth - AppDelete) to nuke it. This apparently cleans up everything on the Mac side.
I then used the DataPurge UI to nuke the tasks (after doing another backup of course) as it was hanging on tasks.
I then did a reinstall.
After doing all of that, It now works. I'm not sure why this works, but it does so that's all I care about.
