[Plugin: EZPZ One Click Backup] EZPZ Doesn't work with wordpress 3.3.1

Since the major update of EZPZ it no longer works with wordpress on any of the websites I maintain. On the initial install/reinstall once the schedule is set a row of script errors appear at the top.
The background backup never completes.
The manual backup completes but won’t connect to the FTP Server.
Schedules never run.
Changing the random folder creates a script error.

The script errors seem to be ‘file not found’ errors for other scripts or to the backup folder.

Most of my wordpress installs are in subfolders, this could be the problem, but EZPZ worked ok before the upgrades.
