I extracted 0.33.4 (WinXP 32-bit, normally run as non-admin user, admin user extracted the new version to the Program Files dir).
I'm not sure I recollect all the details correctly, but when it first ran (or maybe when it first shut down after running the new version) it displayed an error dialogue for some problem with a fairly long filename (using a GUID or hash as part of the name?) I believe the next time it ran the download queue had been wiped. In addition, now on shutdown it complains about not being able to create C:\Program Files\alt.binz\queue\queue.idx. I can probably change the file permissions so that programs executing as the non-administrative user can create folders in the Program Files\alt.binz dir...but alt.binz really should be using the user's profile to store configuration such as this so that one doesn't have to - and either way it shouldn't wipe the queue.
I checked the alt.binz\misc dir and the latest queue-related file appears to be a copyof_queue.abz file that is five weeks old
I haven't found a more recent queue file anywhere else yet. I'll see if I can use this old version + cached files in the NZB dir to reconstruct the missing additions to the queue, but that won't weed out missing deletions from the queue.
It also seems that starting 0.33.4 touches the file modification date of the binaries in that folder (par2.exe and unrar.dll), which is weird and somewhat suspicious and doesn't seem necessary.
